84db6f27b2 soc: ep93xx: drop reference to removed EP93XX_SOC_COMMON config 
Commit 6eab0ce6e1 ("soc: Add SoC driver for Cirrus ep93xx") adds the
config EP93XX_SOC referring to the config EP93XX_SOC_COMMON.

Within the same patch series of the commit above, the commit 046322f1e1
("ARM: ep93xx: DT for the Cirrus ep93xx SoC platforms") then removes the
config EP93XX_SOC_COMMON. With that the reference to this config is
obsolete.

Simplify the expression in the EP93XX_SOC config definition.

53cf1dc480 clk: ep93xx: Fix off by one in ep93xx_div_recalc_rate() 
The psc->div[] array has psc->num_div elements.  These values come from
when we call clk_hw_register_div().  It's adc_divisors and
ARRAY_SIZE(adc_divisors)) and so on.  So this condition needs to be >=
instead of > to prevent an out of bounds read.

Add compulsory device tree support to the Cirrus ep93xx ARMv4 platform.

- select PINCTRL_EP93xx
- select COMMON_CLK_EP93XX, as clock driver moved out of platform code
- select ARCH_HAS_RESET_CONTROLLER

Select ARM_ATAG_DTB_COMPAT to update device tree with information
about memory passed from bootloader.

We have to leave all MACH options as they are used for board checking
before decomp, to turn off watchdog and ethernet DMA.

- pinctrl

avoid conflict writing to swlocked parts of DEVCFG.

Provide common resources such as base, regmap and spinlock via auxiliary

cbe8e464eb gpio: ep93xx: split device in multiple 
Prepare ep93xx SOC gpio to convert into device tree driver:
- dropped banks and legacy defines
- split AB IRQ and make it shared

We are relying on IRQ number information A, B ports have single shared
IRQ, while F port have dedicated IRQ for each line.

Also we had to split single ep93xx platform_device into multiple, one
for each port, without this we can't do a full working transition from
legacy platform code into device tree capable. All GPIO_LOOKUP were
change to match new chip namings.

c7f06284a6 ep93xx: clock: Fix off by one in ep93xx_div_recalc_rate() 
The psc->div[] array has psc->num_div elements.  These values come from
when we call clk_hw_register_div().  It's adc_divisors and
ARRAY_SIZE(adc_divisors)) and so on.  So this condition needs to be >=
instead of > to prevent an out of bounds read.
