Grygorii Strashko 6075a8b2b6 gpio: davinci: don't create irq_domain in case of unbanked irqs
The system may crash if:
- there are more than 1 banks
- unbanked irqs are enabled
- someone will call gpio_to_irq() for GPIO from bank2 or above

Hence, fix it by not creating irq_domain if unbanked irqs are enabled
and correct gpio_to_irq_banked() to handle this properly.

Grygorii Strashko 0d978eb734 gpio: davinci: use chained_irq_enter/chained_irq_exit API
It's unsafe to call IRQ chip callbacks (.irq_mask/irq_unmask/irq_ack)
from chained IRQ handler directly. Because, Davinci GPIO block is used
by different SoCs, which, in turn, have different Main IRQ controllers
(Davinci - aintc, cp-intc; Keystone - arm-gic) which may introduce
diffrent set of IRQ chip callbacks. As result, call of
gpio_irq_handler() on Keysone will simply cause crash the system,
because ARM-GIC implements .irq_eoi() instead of .irq_ack().

Hence, fix it by using Kernel chained_irq_enter/chained_irq_exit APIs as
they are intended to handle exact such cases.

Grygorii Strashko c21d500bdc gpio: davinci: get rid of DAVINCI_N_GPIO
Since Davinci GPIO driver is moved to support gpiolib it has to use
ARCH_NR_GPIOS (can be configured using CONFIG_ARCH_NR_GPIO Kconfig
option) configuration instead of any mach/platform specific options.

Hence, replace private DAVINCI_N_GPIO with common ARCH_NR_GPIOS. This is
safe because default value for ARCH_NR_GPIOS=256 and maximum number of
supported GPIOs for Davinci is DAVINCI_N_GPIO=144.

More over, this is one of steps to re-use Davinci GPIO driver by other
mach/platform.

Lad, Prabhakar 388291c3a1 gpio: davinci: use {readl|writel}_relaxed() instead of __raw_*
This patch replaces the __raw_readl/writel with
{readl|writel}_relaxed(), Altough the code runs on ARMv5
based SOCs, changing this will help using code for other
use cases (like with big-endian machines).

Bastian Hecht 20bdcab826 serial: sh-sci: Add OF support
Extend the driver to with support for SCIx device tree bindings. A
minimal set of features is supported, additional properties can be added
later should the need to describe more device features arise.

SCIFA ports on sh7723 and sh7724 seem to use a sampling rate of half the

baud rate calculation algorithm. The algorithm ID will be removed from
