The patch spi: bcm63xx-hsspi: Really keep pll clk enabled has been applied to the spi tree at https://git.kernel.org/pub/scm/linux/kernel/git/broonie/spi.git All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark >From 51bddd4501bc414b8b1e8f4d096b4a5304068169 Mon Sep 17 00:00:00 2001 From: Christophe JAILLET <christophe.jaillet@xxxxxxxxxx> Date: Fri, 28 Feb 2020 22:38:38 +0100 Subject: [PATCH] spi: bcm63xx-hsspi: Really keep pll clk enabled The purpose of commit 0fd85869c2a9 ("spi/bcm63xx-hsspi: keep pll clk enabled") was to keep the pll clk enabled through the lifetime of the device. In order to do that, some 'clk_prepare_enable()'/'clk_disable_unprepare()' calls have been added in the error handling path of the probe function, in the remove function and in the suspend and resume functions. However, a 'clk_disable_unprepare()' call has been unfortunately left in the probe function. So the commit seems to be more or less a no-op. Axe it now, so that the pll clk is left enabled through the lifetime of the device, as described in the commit.
