Subject: [PATCH 00/16] mmc: sdhci-pltfm: Minor clean up
Date: Fri, 11 Aug 2023 16:03:35 +0300	[thread overview]
Message-ID: <20230811130351.7038-1-adrian.hunter@intel.com> (raw)

Hi

sdhci_pltfm_unregister() does:

	clk_disable_unprepare(pltfm_host->clk)

which prevents drivers from using devm_clk_get_enabled() or similar.

Move it out, and where drivers are doing devm_clk_get*() immediately
followed by clk_prepare_enable(), combine them into devm_clk_get_*enabled().

sdhci_pltfm_register() and sdhci_pltfm_unregister() are not paired functions.
That are just helpers and effectively get renamed:

	sdhci_pltfm_register() -> sdhci_pltfm_init_and_add_host()
	sdhci_pltfm_unregister() -> sdhci_pltfm_remove()

Please note, the patches are based on top of some 
"Convert to platform remove callback returning void"
patches by Yangtao Li, which were posted here:

	https://lore.kernel.org/linux-mmc/20230727070051.17778-1-frank.li@vivo.com/
