Merge tag 'clk-microchip-6.5-2' of https://git.kernel.org/pub/scm/linux/kernel/git/at91/linux into clk-microchip

Browse Source 
Pull Microchip clk driver updates from Claudiu Beznea:

It contains support for parent_data, parent_hw in AT91 clock drivers
used by SAMA7G5 SoC (e.g. main, master, generic, peripheral, programmable,
system, utmi, slow clocks) and also the update of SAMA7G5 to use
this new support.

* tag 'clk-microchip-6.5-2' of https://git.kernel.org/pub/scm/linux/kernel/git/at91/linux:
  clk: at91: sama7g5: s/ep_chg_chg_id/ep_chg_id
  clk: at91: sama7g5: switch to parent_hw and parent_data
  clk: at91: sckc: switch to parent_data/parent_hw
  clk: at91: clk-sam9x60-pll: add support for parent_hw
  clk: at91: clk-utmi: add support for parent_hw
  clk: at91: clk-system: add support for parent_hw
  clk: at91: clk-programmable: add support for parent_hw
  clk: at91: clk-peripheral: add support for parent_hw
  clk: at91: clk-master: add support for parent_hw
