Subject: [PATCH 00/13] Mediatek MT6735 main clock and reset drivers

From: Yassine Oudjana <y.oudjana@...tonmail.com>

This series adds support for the main clock and reset controllers on the
Mediatek MT6735 SoC:
- apmixedsys (global PLLs)
- topckgen (global divisors and muxes)
- infracfg (gates and resets for internal components)
- pericfg (gates and resets for peripherals)

MT6735 has other more specialized clock controllers, support for which is
not included in this series:
- imgsys (camera)
- mmsys (display)
- vdecsys (video decoder)
- audsys (audio)

Some symbols in common objects are exported to get the drivers to compile
as modules, and mtk_unregister_reset_controller() is implemented to allow
for unregistering reset controllers in the infracfg and pericfg drivers
when unloading them.

Yassine Oudjana (13):
  dt-bindings: clock: Add Mediatek MT6735 clock bindings
  dt-bindings: reset: Add MT6735 reset bindings
  dt-bindings: arm: mediatek: Add MT6735 clock controller compatibles
  clk: composite: Export clk_unregister_composite
  clk: mediatek: Export mtk_free_clk_data
  clk: mediatek: Add driver for MT6735 apmixedsys
  clk: mediatek: Add driver for MT6735 topckgen
  clk: mediatek: gate: Export mtk_clk_register_gates_with_dev
  clk: mediatek: reset: Export mtk_register_reset_controller symbols
  clk: mediatek: reset: Return mtk_reset pointer on register
  clk: mediatek: reset: Implement mtk_unregister_reset_controller() API
  clk: mediatek: Add driver for MT6735 infracfg
  clk: mediatek: Add driver for MT6735 pericfg
