Arnd Bergmann 12c3dca25d ARM: ep93xx: remove MaverickCrunch support
The MaverickCrunch support for ep93xx never made it into glibc and
was removed from gcc in its 4.8 release in 2012. It is now one of
the last parts of arch/arm/ that fails to build with the clang
integrated assembler, which is unlikely to ever want to support it.

The two alternatives are to force the use of binutils/gas when
building the crunch support, or to remove it entirely.

According to Hartley Sweeten:

 "Martin Guy did a lot of work trying to get the maverick crunch working
  but I was never able to successfully use it for anything. It "kind"
  of works but depending on the EP93xx silicon revision there are still
  a number of hardware bugs that either give imprecise or garbage results.

  I have no problem with removing the kernel support for the maverick
  crunch."

Unless someone else comes up with a good reason to keep it around,
remove it now. This touches mostly the ep93xx platform, but removes
a bit of code from ARM common ptrace and signal frame handling as well.

If there are remaining users of MaverickCrunch, they can use LTS
kernels for at least another five years before kernel support ends.

spi: ep93xx: Repair SPI CS lookup tables
The actual device name of the SPI controller being registered on EP93xx is
"spi0" (as seen by gpiod_find_lookup_table()). This patch fixes all
relevant lookup tables and the following failure (seen on EDB9302):

ep93xx-spi ep93xx-spi.0: failed to register SPI master
ep93xx-spi: probe of ep93xx-spi.0 failed with error -22

spi: ep93xx: Convert to use CS GPIO descriptors
This converts the EP93xx SPI master driver to use GPIO
descriptors for chip select handling.

EP93xx was using platform data to pass in GPIO lines,
by converting all board files to use GPIO descriptor
tables the core will look up the GPIO lines from the
SPI device in the same manner as for device tree.

Linus Walleij b2e6355559 i2c: gpio: Convert to use descriptors
This converts the GPIO-based I2C-driver to using GPIO
descriptors instead of the old global numberspace-based
GPIO interface. We:

- Convert the driver to unconditionally grab two GPIOs
  from the device by index 0 (SDA) and 1 (SCL) which
  will work fine with device tree and descriptor tables.
  The existing device trees will continue to work just
  like before, but without any roundtrip through the
  global numberspace.

- Brutally convert all boardfiles still passing global
  GPIOs by registering descriptor tables associated with
  the devices instead so this driver does not need to keep
  supporting passing any GPIO numbers as platform data.

There is no stepwise approach as elegant as this, I
strongly prefer this big hammer over any antsteps for this
conversion. This way the old GPIO numbers go away and
NEVER COME BACK.

Special conversion for the different boards utilizing
I2C-GPIO:

- EP93xx (arch/arm/mach-ep93xx): pretty straight forward as
  all boards were using the same two GPIO lines, just define
  these two in a lookup table for "i2c-gpio" and register
  these along with the device. None of them define any
  other platform data so just pass NULL as platform data.
  This platform selects GPIOLIB so all should be smooth.
  The pins appear on a gpiochip for bank "G" as pins 1 (SDA)
  and 0 (SCL).

- IXP4 (arch/arm/mach-ixp4): descriptor tables have to
  be registered for each board separately. They all use
  "IXP4XX_GPIO_CHIP" so it is pretty straight forward.
  Most board define no other platform data than SCL/SDA
  so they can drop the #include of <linux/i2c-gpio.h> and
  assign NULL to platform data.

  The "goramo_mlr" (Goramo Multilink Router) board is a bit
  worrisome: it implements its own I2C bit-banging in the
  board file, and optionally registers an I2C serial port,
  but claims the same GPIO lines for itself in the board file.
  This is not going to work: there will be competition for the
  GPIO lines, so delete the optional extra I2C bus instead, no
  I2C devices are registered on it anyway, there are just hints
  that it may contain an EEPROM that may be accessed from
  userspace. This needs to be fixed up properly by the serial
  clock using I2C emulation so drop a note in the code.

- KS8695 board acs5k (arch/arm/mach-ks8695/board-acs5.c)
  has some platform data in addition to the pins so it needs to
  be kept around sans GPIO lines. Its GPIO chip is named
  "KS8695" and the arch selects GPIOLIB.

- PXA boards (arch/arm/mach-pxa/*) use some of the platform
  data so it needs to be preserved here. The viper board even
  registers two GPIO I2Cs. The gpiochip is named "gpio-pxa" and
  the arch selects GPIOLIB.

- SA1100 Simpad (arch/arm/mach-sa1100/simpad.c) defines a GPIO
  I2C bus, and the arch selects GPIOLIB.

- Blackfin boards (arch/blackfin/bf533 etc) for these I assume
  their I2C GPIOs refer to the local gpiochip defined in
  arch/blackfin/kernel/bfin_gpio.c names "BFIN-GPIO".
  The arch selects GPIOLIB. The boards get spiked with
  IF_ENABLED(I2C_GPIO) but that is a side effect of it
  being like that already (I would just have Kconfig select
  I2C_GPIO and get rid of them all.) I also delete any
  platform data set to 0 as it will get that value anyway
  from static declartions of platform data.

- The MIPS selects GPIOLIB and the Alchemy machine is using
  two local GPIO chips, one of them has a GPIO I2C. We need
  to adjust the local offset from the global number space here.
  The ATH79 has a proper GPIO driver in drivers/gpio/gpio-ath79.c
  and AFAICT the chip is named "ath79-gpio" and the PB44
  PCF857x expander spawns from this on GPIO 1 and 0. The latter
  board only use the platform data to specify pins so it can be
  cut altogether after this.

- The MFD Silicon Motion SM501 is a special case. It dynamically
  spawns an I2C bus off the MFD using sm501_create_subdev().
  We use an approach to dynamically create a machine descriptor
  table and attach this to the "SM501-LOW" or "SM501-HIGH"
  gpiochip. We use chip-local offsets to grab the right lines.
  We can get rid of two local static inline helpers as part
  of this refactoring.

and replace the machine descriptor .timer field with the initialization
function itself.

This will enable moving timer drivers into drivers/clocksource without
having to place a public prototype of each struct sys_timer object into
include/linux; the intent is to create a single of_clocksource_init()
function that determines which timer driver to initialize by scanning
the device dtree, much like the proposed irqchip_init() at:

This is stuff that does not fit well into another category and in
 particular is not related to a particular board. The largest part
 in here is extending the am33xx support in the omap platform.

Hartley Sweeten b370e082e7 ARM: 5992/1: ep93xx: pass platform startup data as __initdata
A number of the peripherals for the ep93xx are registered at
startup using platform_data that is passed from the board init
code to the core code.  This data is then copied to a local
static variable in the core code.  Since the data is copied,
the original data can be marked as __initdata and discarded
after startup is complete.

This adds the __initdata tag to all the appropriate data in
the various ep93xx board init's.  Specifically, all the
struct ep93xx_eth_data, struct ep93xxfb_mach_info, and
struct i2c_gpio_platform_data.

Also, document the various registration functions and note
what data should be marked as __initdata.

While here, also cleanup a couple over zealous whitespace tabs.

Hartley Sweeten 6531a991f9 ARM: 5754/1: ep93xx: update i2c support
Update the ep93xx i2c support:

  1) The platform init code passes the configuration data for the
     i2c-gpio driver.  This allows any gpio pin do be used for the
     sda and scl pins.  It also allows the platform to specify the
     udelay and timeout.
  2) Program the gpio configuration register to enable/disable the
     open drain drivers.  Note that this really only works if the
     sda and scl pins are set to EP93XX_GPIO_LINE_EEDAT and
     EP93XX_GPIO_LINE_EECLK.
  3) Update the edb93xx.c platform init to use the new support.
