Subject: [PATCH master 3/3] clk: imx: imx8mp: sync with Linux v6.9-rc3
Date: Fri, 19 Apr 2024 08:10:03 +0200	[thread overview]
Message-ID: <20240419061003.2590849-4-a.fatoum@pengutronix.de> (raw)
In-Reply-To: <20240419061003.2590849-1-a.fatoum@pengutronix.de>

This sync is mainly done to pull in Linux commit c277ca155d2f0:

 |  clk: imx8m: fix bus critical clk registration
 |
 |  noc/axi/ahb are bus clk, not peripheral clk.
 |  Since peripheral clk has a limitation that for peripheral clock slice,
 |  IP clock slices must be stopped to change the clock source.
 |
 |  However if the bus clk is marked as critical clk peripheral, the
 |  assigned clock parent operation will fail.
 |
 |  So we added CLK_SET_PARENT_GATE flag to avoid glitch.
 |
 |  And add imx8m_clk_hw_composite_bus_critical for bus critical clock usage
 |
 |  Fixes: 936c383673b9e ("clk: imx: fix composite peripheral flags")

Without this, attempts to reparent e.g. noc_io would hang.
