clk: ti: Update component clocks to use ti_dt_clk_name()

2022-03-11T02:55:59Z

Let's update all the TI component clocks to use ti_dt_clk_name() instead of devicetree node name if available. Signed-off-by: Tony Lindgren Link: https://lore.kernel.org/r/20220204071449.16762-9-tony@atomide.com Signed-off-by: Stephen Boyd

clk: ti: divider: convert to use min,max,mask instead of width

2019-10-31T13:32:36Z

The existing width field used to check divider validity does not provide enough protection against bad values. For example, if max divider value is 4, the smallest all-1 bitmask that can hold this value is 7, which allows values higher than 4 to be used. This typically causes unpredictable results with hardware. So far this issue hasn't been noticed as most of the dividers actually have maximum values which fit the whole bitfield, but there are certain clocks for which this is a problem, like dpll4_m4 divider on omap3 devices. Thus, convert the whole validity logic to use min,max and mask values for determining if a specific divider is valid or not. This prevents the odd cases where bad value would otherwise be written to a divider config register. Signed-off-by: Tero Kristo Tested-by: Adam Ford

clk: ti: divider: cleanup ti_clk_parse_divider_data API

2019-10-31T13:32:34Z

Cleanup the ti_clk_parse_divider_data to pass the divider data struct directly instead of individual values of it. This makes it easier to modify the implementation later on. Signed-off-by: Tero Kristo Tested-by: Adam Ford

clk: ti: divider: cleanup _register_divider and ti_clk_get_div_table

2019-10-31T13:32:32Z

Cleanup couple of TI divider clock internal APIs. These currently pass huge amount of parameters, which makes it difficult to track what is going on. Abstract most of these under struct clk_omap_div which gets passed over the APIs. Signed-off-by: Tero Kristo Tested-by: Adam Ford

clk: ti: remove usage of CLK_IS_BASIC

2019-02-15T14:46:22Z

Remove the usage of CLK_IS_BASIC flag completely from TI clock driver. In most cases, the use is completely redundant, but in some cases we need to use the new API to check if the clock is an OMAP clock or not. Signed-off-by: Tero Kristo Acked-by: Tony Lindgren Tested-by: Keerthy

clk: ti: Fix error handling in ti_clk_parse_divider_data()

2019-01-24T19:23:32Z

The ti_clk_parse_divider_data() function is only called from _get_div_table_from_setup(). That function doesn't look at the return value but instead looks at the "*table" pointer. In this case, if the kcalloc() fails then *table is NULL (which means success). It should instead be an error pointer. The ti_clk_parse_divider_data() function has two callers. One checks for errors and the other doesn't. I have fixed it so now both handle errors.
