Commit 6c0afb50 ("clk: ti: convert to use proper register definition for all accesses") converted all register accesses in the TI clk driver to use a proper struct instead of a void pointer casted struct that fits into a u32. Unfortunately, it missed a conversion here in the didivder code, leading to a compiler warning like so: drivers/clk/ti/divider.c: In function 'ti_clk_register_divider': drivers/clk/ti/divider.c:460:8: error: 'reg' may be used uninitialized in this function [-Werror=maybe-uninitialized] Treating a 'u32' variable as a structure leads to a stack overflow here, and the register address we pass down is never initialized. Convert this part of the code as well so things work properly. Fixes: 6c0afb50 ("clk: ti: convert to use proper register definition for all accesses") Signed-off-by:

* Multiplications for the size determination of memory allocations indicated that array data structures should be processed. Thus use the corresponding function "kcalloc". This issue was detected by using the Coccinelle software. * Replace the specification of data types by pointer dereferences to make the corresponding size determination a bit safer according to the Linux coding style convention.

When none of the OMAP4-generation SoCs are enabled, we run into a link error for am43xx/am43xx: drivers/clk/ti/dpll.o: In function `of_ti_am3_dpll_x2_setup': dpll.c:(.init.text+0xd8): undefined reference to `clkhwops_omap4_dpllmx' This is easily fixed by adding another #ifdef. While looking at the code, I also spotted another problem with the assignment of hw_ops variable that is not used again later. I'm changing this to setting clk_hw->ops instead, which I guess is what was intended here. Fixes: 473adbf4 ("clk: ti: dpll44xx: fix clksel register initialization") Signed-off-by:

cs2000 can select Static/Dynamic ratio based Frequency Synthesizer Mode, it can select 20.12 High Multiplier interpret for 32-bit User Defined Ratio if Dynamic ratio mode. Otherwise it should select 12.20 High Accuracy mode. Current cs2000 is supporting Static ratio mode only, so it should select 12.20 High Accuracy mode, not 20.12 High Multiplier mode. This patch fixes it. Signed-off-by:

DEVICE_CFG2 can select ratio from user defined ratio and LOCKCLK is for it. But current driver sets fixed 0 value. This patch fixes it. Note is that current cs2000 driver is using/supporting only ratio0 (= ch0) now. DEVICE_CFG2 can select STATIC/DYNAMIC ratio mode, and current cs2000 driver is selecting STATIC mode, but it was not understandable on current code. This patch also solve this issue. Signed-off-by:

Due to timing requirements, TI and Conexant manage the audio reference clock from their ASoC codec drivers using the "mclk" string. This patch adds another lookup for the "pmc_plt_clk_3" clock to avoid Intel-specific tests in those codec drivers and use code as-is. To avoid a leak, clk_add_alias() is not used in this patch. Instead the lookup is created manually as part of the .probe() step and dropped in the .remove() step. "pmc_plt_clk_3" is used exclusively for audio on all known Baytrail/CherryTrail designs and is e.g. routed on the MCLK (pin 26) of the MinnowBoardMAX Turbot LSE connector. Signed-off-by:

Update IDT VersaClock 5 driver to support 5P49V5935. This chip has two clock inputs (internal XTAL or external CLKIN), four fractional dividers (FODs) and five clock outputs (four universal clock outputs and one reference clock output at OUT0_SELB_I2C). Current driver supports up to 2 FODs and up to 3 clock outputs. This patch sets max number of supported FODs to 4 and max number of supported clock outputs to 5. Signed-off-by:

Introduce vc5_chip_info structure to describe features of a particular VC5 chip (id, number of FODs, number of outputs, flags). For now flags are only used to indicate if chip has internal XTAL. vc5_chip_info is set on probe from the matched of_device_id->data. Also add defines to specify maximum number of FODs and clock outputs supported by the driver. With these changes it should be easier to extend driver to support more VC5 models. Signed-off-by:
