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: autoidle: add checks against NULL pointer reference

2020-09-22T20:00:07Z

The clk pointer passed to omap2_clk_(deny|allow)_idle can be NULL, so add checks for this. Reported-by: Dan Murphy Signed-off-by: Tero Kristo Link: https://lore.kernel.org/r/20200907082600.454-2-t-kristo@ti.com Signed-off-by: Stephen Boyd

clk: ti: check clock type before doing autoidle ops

2019-02-15T14:47:55Z

Code might use autoidle api with clocks not being omap2 clocks, so check if clock type is really omap2. Signed-off-by: Andreas Kemnade Acked-by: Tony Lindgren Tested-by: Keerthy Signed-off-by: Tero Kristo

clk: ti: add a usecount for autoidle

2019-02-15T14:47:55Z

Multiple users might deny autoidle on a clock. So we should have some counting here, also according to the comment in _setup_iclk_autoidle(). Also setting autoidle regs is not atomic, so there is another reason for locking. Signed-off-by: Andreas Kemnade Acked-by: Tony Lindgren Tested-by: Keerthy Signed-off-by: Tero Kristo

clk: ti: move clk_hw_omap list handling under generic part of the driver

2019-02-15T14:46:21Z

Currently the clk_hw_omap list is handled under the autoidle code, but it should be accessible generically. Add a few APIs towards this, and update the autoidle code to use the generic implementations. Signed-off-by: Tero Kristo Acked-by: Tony Lindgren Tested-by: Keerthy

clk: ti: convert to use proper register definition for all accesses

2017-03-08T11:06:15Z

Currently, TI clock driver uses an encapsulated struct that is cast into a void pointer to store all register addresses. This can be considered as rather nasty hackery, and prevents from expanding the register address field also. Instead, replace all the code to use proper struct in place for this, which contains all the previously used data. This patch is rather large as it is touching multiple files, but this can't be split up as we need to avoid any boot breakage. Signed-off-by: Tero Kristo Acked-by: Tony Lindgren

clk: ti: Convert to clk_hw based provider APIs

2015-08-24T23:48:58Z

We're removing struct clk from the clk provider API, so switch this code to using the clk_hw based provider APIs. Acked-by: Tero Kristo Signed-off-by: Stephen Boyd

clk: ti: Remove CLK_IS_BASIC check

2015-08-24T23:48:44Z

This code is never called with a basic clock type, so the check here is not doing anything useful and is blocking the removal of __clk_get_flags(). Remove the check so we can delete the __clk_get_flags() API. Acked-by: Tero Kristo Signed-off-by: Stephen Boyd

clk: ti: move some public definitions to private header

2015-06-02T09:31:45Z

Several exported TI clock driver features are no longer needed outside the clock driver itself, thus move all of these to the driver private header file. Also, update some of the driver files to actually include this header. Signed-off-by: Tero Kristo
