A multiplication for the size determination of a memory allocation indicated that an array data structure should be processed. Thus use the corresponding function "kmalloc_array". This issue was detected by using the Coccinelle software. Signed-off-by:

The addition of many gate clocks added two entries in an array for the same value: drivers/clk/meson/meson8b.c:479:10: error: initialized field overwritten [-Werror=override-init] [CLKID_GCLK_VENCI_INT] = &meson8b_gclk_venci_int.hw, [CLKID_GCLK_VENCI_INT] = &meson8b_gclk_vencp_int.hw, This was clearly an accident, and since all other identifiers are listed in the order in which they are defined, I'm changing the first one to CLKID_GCLK_VENCI_INT0, making it all consistent again.

This commit introduces the clocks found in the Allwinner A33 CCU. Since this SoC is very similar to the A23, and we share a significant share of the DTSI, the clock IDs that are going to be used will also be shared with the A23, hence the name of the various header files. Signed-off-by:

Some dividers might have a maximum value that is lower than the width of the register. Add a field to _ccu_div to handle those case properly. If the field is set to 0, the code will assume that the maximum value is the maximum one that can be used with the field register width. Otherwise, we'll use whatever value has been set.

This patch adds code instantiating the EPLL, which is used as the audio subsystem's root clock. The requirement to specify the external root clock in clocks property is documented. Having the consumer 'clocks' property ensures proper initialization order by explicitly specifying dependencies in DT. It prevents situations when the SoC's clock controller driver has initialized, the external oscillator clock is not yet registered and setting clock frequencies through assigned-clock-rates property doesn't work properly due to unknown external oscillator frequency.

Exynos5410 Audio Subsystem Clock Controller, comparing to the already supported IP block revisions, has additionally an I2S_MST divider so a new compatible string is added. It is not clear from the Exynos5410 User's Manual released on 2012.03.09 where in the clock tree the I2S_MST clock divider can be found exactly so this clock is left unimplemented for now.

This patch moves the samsung_cmu_info struct instances to initconst section, this decreases the kernel image size by 784 bytes, which makes zImage smaller by 480 bytes. The patch increases .init.rodata section size by 780 bytes but decreases .init.text section size by 1564 bytes. Size of the drivers/clk/samsung/clk-exynos5260.o object file is 29100 bytes without the patch and 28316 after applying the patch. The section size differences are as below: 15c15 < 3 .init.text 000006b8 00000000 00000000 00000034 2**2 --- > 3 .init.text 0000009c 00000000 00000000 00000034 2**2 25c25 < 8 .init.rodata 00003f6c 00000000 00000000 00002f20 2**2 --- > 8 .init.rodata 00004278 00000000 00000000 00002904 2**2 Signed-off-by:

Add myself to the SAMSUNG SOC CLOCK DRIVERS entry, I'm going to review and test related patches as supporter. I can access all the datasheet of Exynos SoC series and can do tests on Exynos based boards. I have implemented the exynos4415/5433 clock drivers and co-authored the exynos3250 clock driver. While at it, add missing paths of the exynos clock driver files. Cc: Tomasz Figa <tomasz.figa@gmail.com> Signed-off-by:
