Subject: [PATCH v4 0/10] Add mt7629 and fix mt7628 pwm
Date: Tue, 20 Aug 2019 09:40:15 +0800 [thread overview]
Message-ID: <1566265225-27452-1-git-send-email-sam.shih@mediatek.com> (raw)
From: sam shih <sam.shih@mediatek.com>
Changes since v4:
- Follow reviewer's comments (v3: pwm: mediatek: add a property "num-pwms")
Move the changes of droping the check for of_device_get_match_data
returning non-NULL to next patch
- Follow reviewers's comments
(v3: pwm: mediatek: allocate the clks array dynamically)
1. use pc->soc->has_clks to check clocks exist or not.
2. Add error message when probe() unable to get clks
- Fixes bug when SoC is old mips which has no complex clock tree.
if clocks not exist, use the new property from DT to apply period caculation;
otherwise, use clk_get_rate to get clock frequency and apply period caculation.
Changes since v3:
- add a new property "clock-frequency" and fix mt7628 pwm
- add mt7629 pwm support
Changes since v2:
- use num-pwms instead of mediatek,num-pwms.
- rename the member from num_pwms to fallback_num_pwms to make it
more obvious that it doesn't represent the actually used value.
- add a dev_warn and a expressive comment to help other developers
to not start adding num_pwms in the compatible_data.
Changes since v1:
- add some checks for backwards compatibility.
