The Rapid General-Purpose Input and Output with 2 Ports (RGPIO2P)
on MX7ULP is similar to GPIO on Vibrid. But unlike Vibrid, the
RGPIO2P has an extra Port Data Direction Register (PDDR) used
to configure the individual port pins for input or output.
We introduce a bool have_paddr with fsl_gpio_soc_data data
to distinguish this differences. And we support getting the output
status by checking the GPIO direction in PDDR.

Add fallback compatibility string for R-Car Gen 1, 2 and 3.
In the case of Renesas R-Car hardware we know that there are generations of
SoCs, f.e. Gen 1 and 2. But beyond that its not clear what the relationship
between IP blocks might be. For example, I believe that r8a7790 is older
than r8a7791 but that doesn't imply that the latter is a descendant of the
former or vice versa.
We can, however, by examining the documentation and behaviour of the
hardware at run-time observe that the current driver implementation appears
to be compatible with the IP blocks on SoCs within a given generation.
For the above reasons and convenience when enabling new SoCs a
per-generation fallback compatibility string scheme being adopted for
drivers for Renesas SoCs.
Also deprecate renesas,gpio-rcar as its name is more generic than its
implementation.

Now IRQ mappings are always created for all (allowed) GPIOs in gpiochip in
gpiochip_irqchip_add_key() which goes against the idea of SPARSE_IRQ and,
as result, leads to:
- increasing of memory consumption for IRQ descriptors most of which will
never ever be used (espessially on platform with a high number of GPIOs).
(sizeof(struct irq_desc) == 256 on my tested platforms)
- imposibility to use GPIO irqchip APIs by gpio drivers when HW implements
GPIO IRQ functionality as IRQ crossbar/router which has only limited
number of IRQ outputs (example from [1], all GPIOs can be mapped on only 8
IRQs).
Hence, remove static IRQ mapping code from gpiochip_irqchip_add_key() and
instead replace irq_find_mapping() with irq_create_mapping() in
gpiochip_to_irq(). Also add additional gpiochip_irqchip_irq_valid() calls
in gpiochip_to_irq() and gpiochip_irq_map().
After this change gpio2irq mapping will happen the following way when GPIO
irqchip APIs are used by gpio driver:
- IRQ mappings will be created statically if driver passes first_irq>0
vlaue in gpiochip_irqchip_add_key().
- IRQ mappings will be created dynamically from gpio_to_irq() or
of_irq_get().
Tested on am335x-evm and dra72-evm-revc.
- dra72-evm-revc: number of created irq mappings decreased from 402 -> 135
Mem savings 267*256 = 68352 (66kB)
- am335x-evm: number of created irq mappings decreased from 188 -> 63
Mem savings 125*256 = 32000 (31kB)

- MicroMIPS uses bit 0 of the PC to indicate microMIPS mode. Make

- Prevent configuring the kernel for both microMIPS and MT. There are

USB: serial: cp210x: add support for Qivicon USB ZigBee dongle
An mtdblock regression occurred in -rc1 (all writes were broken!), in the
process of some block subsystem refactoring. Noticed and fixed last week, but
I'm a little slow on the uptake.

mtd: blkdevs: Fix mtd block write failure
All the MTD block write requests are failing with
following error messages
mkfs.ext4 /dev/mtdblock0
print_req_error: I/O error, dev mtdblock0, sector 0
Buffer I/O error on dev mtdblock0, logical block 0,
lost async page write
The control is going to default case after block write request
because of missing return.
Fixes: commit 2a842acab1 ("block: introduce new block status code type")
