* clk: davinci: remove PLL and PSC clocks for DaVinci DM644x and DM646xLukas Bulwahn2022-08-311-6/+0
| | | | | | | | | | | | | | Commit 7dd33764486d ("ARM: davinci: Delete DM644x board files") and commit b4aed01de486 ("ARM: davinci: Delete DM646x board files") removes the support for DaVinci DM644x and DM646x boards. Hence, remove the PLL and PSC clock descriptions for those boards as well.

* clk: davinci: psc: allow for dev == NULLDavid Lechner2018-05-301-14/+44
| | | | | | | | | | | | On some davinci SoCs, we need to register the PSC clocks during early boot because they are needed for clocksource/clockevent. These changes allow for dev == NULL because in this case, we won't have a platform device for the clocks.

* clk: davinci: New driver for davinci PSC clocksDavid Lechner2018-03-201-0/+542
This adds a new driver for mach-davinci PSC clocks. This is porting the code from arch/arm/mach-davinci/psc.c to the common clock framework and is converting it to use regmap to simplify the code. Additionally, it adds device tree support for these clocks. Note: although there are similar clocks for TI Keystone we are not able to share the code for a few reasons. The keystone clocks are device tree only and use legacy one-node-per-clock bindings. Also the keystone driver makes the assumption that there is only one PSC per SoC and uses global variables, but here we have two controllers per SoC.
