Subject: [PATCH 0/3] genpd: imx8: support multiple states
Date: Wed, 13 Sep 2023 10:05:35 +0800 [thread overview]
Message-ID: <20230913-multiple-state-scu-v1-0-9d91c6904ffa@nxp.com> (raw)
Patch 1 & 2 are for common code.
Patch 3 is almost same as https://lore.kernel.org/all/20230814104127.1929-8-peng.fan@oss.nxp.com/
For patch 3, I thought of using QoS constraint in the clk-scu driver,
but the clk-scu not support runtime pm, and using simple_qos_governer
would introduce complexity for current SCU Power domain, and the SCU
power domain not only used by clk-scu, but also used by other devices.
So keep current design as NXP downstream which has passed several
rounds LTS releases.
Patch 1&2 has been in NXP LTS for quite some time and pass through
several releases. patch 3 is an update of NXP downstream patch.
