Daniel Golle d518314a1f serial: 8250_mtk: Enable baud clock and manage in runtime PM ... Some MediaTek SoCs got a gated UART baud clock, which currently gets disabled as the clk subsystem believes it would be unused. This results in the uart freezing right after "clk: Disabling unused clocks" on those platforms. Request the baud clock to be prepared and enabled during probe, and to restore run-time power management capabilities to what it was before commit e32a83c70cf9 ("serial: 8250-mtk: modify mtk uart power and clock management") disable and unprepare the baud clock when suspending the UART, prepare and enable it again when resuming it. Fixes: e32a83c70cf9 ("serial: 8250-mtk: modify mtk uart power and clock management") Fixes: b6c7ff2693ddc ("serial: 8250_mtk: Simplify clock sequencing and runtime PM") Cc: stable <stable@kernel.org> Reviewed-by: AngeloGioacchino Del Regno <angelogioacchino.delregno@collabora.com> Signed-off-by: Daniel Golle <daniel@makrotopia.org> Link: https://patch.msgid.link/de5197ccc31e1dab0965cabcc11ca92e67246cf6.1758058441.git.daniel@makrotopia.org Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>		2025-10-22 12:13:54 +02:00
