- Since the time we move to MULTI_IRQ_HANDLER, the 0x7f polling for no
interrupt in icoll_handle_irq() becomes insane, because 0x7f is an
valid interrupt number, the irq of gpio bank 0. That unnecessary
polling results in the driver not detecting when irq 0x7f is active

ARM: EXYNOS: uncompress - print debug messages if DEBUG_LL is defined
Printing low-level debug messages make an assumption that the specified
UART port has been preconfigured by the bootloader. Incorrectly
specified UART port results in system getting stalled while printing the
message "Uncompressing Linux... done, booting the kernel"
This UART port number is specified through S3C_LOWLEVEL_UART_PORT. Since
the UART port might different for different board, it is not possible to
specify it correctly for every board that use a common defconfig file.
Calling this print subroutine only when DEBUG_LL fixes the problem. By
disabling DEBUG_LL in default config file, we would be able to boot
multiple boards with different default UART ports.
With this current approach, we miss the print "Uncompressing Linux...
done, booting the kernel." when DEBUG_LL is not defined.

ARM: shmobile: sh73a0: add support for adjusting CPU frequency
On SH73A0 the output of PLL0 is supplied to two dividers, feeding clock to
the CPU core and SGX. Lower CPU frequencies allow the use of lower supply
voltages and thus reduce power consumption.

ARM: shmobile: r8a7790: Make private clock arrays static
Both clock-r8a7740.c and clock-r8a7790.c define a div4_clks array as
non-static. Compiling support for both SoCs thus result in a symbol
redefinition. Fix it by defining the arrays as static.

Almost all clock needs main clock which is basis clock on r8a7790.
This patch adds it, and, set its parent/ratio via MD pin.
It is based on v0.05 datasheet

R-Car M1 has many clocks, and it is possible to
read/use clock ratio of these clocks from FRQMRx.
But, these ratio are fixed value and
these are decided by MD pin status.
This patch reads MD pin status,
and used fixed ratio clock for other clocks.
It was tesed on bock-w board.

ARM: omap3: clock: fix wrong container_of in clock36xx.c
omap36xx_pwrdn_clk_enable_with_hsdiv_restore expects the parent hw of
the clock to be a clk_hw_omap. However, looking at cclock3xxx_data.c,
all concerned clock have parent defined as clk_divider. Fix the
function to use clk_divider. Tested with 3.9 on dm3730.

ARM: shmobile: sh73a0: Use DEFINE_RES_MEM*() everywhere
Convert code to use DEFINE_RES_MEM*() macros.
These macros were already used in this file,
this change makes their usage consistent throughout the file.

irqchip: Add irqchip_init dummy function
We add an empty irqchip_init dummy function for cases in which
CONFIG_IRQCHIP is not used. In these cases irqchip.c is not compiled,
but a funtion call may still be present in architecture code, that in
runtime doesn't get hit.
E.g. this is needed in the arch/arm/mach-shmobile/intc-r8a7740.c
interrupt setup code where OF use and non OF us is both handled in one
file.

ARM: shmobile: r8a7790: Configure R-Car GPIO for IRQ_TYPE_EDGE_BOTH
"gpio-rcar: Support IRQ_TYPE_EDGE_BOTH" adds support to the R-Car GPIO
driver for IRQ_TYPE_EDGE_BOTH. As hardware support for this feature is
not universal for all SoCs a flag, has_both_edge_trigger, has been
added to the platform data of the driver to allow this feature to be
enabled.

The list of functions selected by the MOD_SEL2 register was missing
an entry. This caused all entries after this to modify the MOD_SEL2
register incorrectly.
This bug showed up when selecting i2c2_c pins on the Renesas Hurricane board.
This bug has been present since pinmux support was added for the
r8a7779 SoC by 881023d28b465eb457067dc8bbca0f24d8b34279 ("sh-pfc: Add
r8a7779 pinmux support") in v3.8-rc4.
