* mmc: Remove dev_err() usage after platform_get_irq()Stephen Boyd2019-09-111-1/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We don't need dev_err() messages when platform_get_irq() fails now that platform_get_irq() prints an error message itself when something goes wrong. Let's remove these prints with a simple semantic patch. // <smpl> @@ expression ret; struct platform_device *E; @@ ret = ( platform_get_irq(E, ...) | platform_get_irq_byname(E, ...) ); if ( \( ret < 0 \| ret <= 0 \) ) { ( -if (ret != -EPROBE_DEFER) -{ ... -dev_err(...); -... } | ... -dev_err(...); ) ... } // </smpl> While we're here, remove braces on if statements that only have one statement (manually).

| | | | | | | | | | | | | | | | | | | | | | | | This commit provides similar cleanups as commit 83eacdfa2529 ("mmc: sdhci: disable the clock in sdhci_pltfm_unregister()") did for unregister hooks. sdhci-brcmstb.c and sdhci-sirf.c implement their own suspend/resume hooks to handle pltfm_host->clk. Move clock handling to sdhci_pltfm.c so that the drivers can reuse sdhci_pltfm_pmops. The following drivers did not previously touch pltfm_host->clk during suspend/resume, but now do: - sdhci-bcm-kona.c - sdhci-dove.c - sdhci-iproc.c - sdhci-pxav2.c - sdhci-tegra.c - sdhci-xenon.c Signed-off-by: Masahiro Yamada <yamada.masahiro@socionext.com> Acked-by: Adrian Hunter <adrian.hunter@intel.com> Acked-by: Al Cooper <alcooperx@gmail.com> Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

* mmc: sdhci-pltfm: Convert to use the SET_SYSTEM_SLEEP_PM_OPSUlf Hansson2016-07-291-4/+3
| | | | | | | | | | | | Move the system PM callbacks within #ifdef CONFIG_PM_SLEEP as to avoid them being build when not used. This also allows us to use the SET_SYSTEM_SLEEP_PM_OPS macro which simplifies the code. Within this context it also makes sense to move the declaration of the struct sdhci_pltfm_pmops, outside the #ifdef CONFIG_PM as the SET_SYSTEM_SLEEP_PM_OPS deals with this. This further simplifies the code. Signed-off-by: Ulf Hansson <ulf.hansson@linaro.org>

| | | | | | | | | | | | | | Since commit cd1e65044d44 ("of/device: Don't register disabled devices"), the disabled device will not be registered at all. So we don't need to do the check again in the platform device driver. And the check in the current code is useless even if we really run into a disabled device. In this case, it just doesn't parse the dtb for the infos such as quirks or clock, but it will continue to try to init the disabled device after that check. So just remove it.

The comment saying "Some PCI-based MFD need the parent here" seem to refer to Timberdale FPGA driver (the only MFD driver registering SDHCI cell, drivers/mfd/timberdale.c) but again, the only situation when parent device matter is runtime PM, which is not implemented for Timberdale.

| | | | | | | | | | | | | | | | | | | The OLPC XO-1.75 laptop includes a SDHCI controller which is 1.8v capable, and it truthfully reports so in its capabilities. This alternate voltage is used for driving new "UHS-I" SD cards at their full speed. However, what the controller doesn't know is that the motherboard physically doesn't have a 1.8v supply available, so attempting to switch to the 1.8v level will result in a situation that cannot be recovered from without physically replugging the SD card. Add a device tree flag that can be used on systems like these, and hook it up to the equivalent SDHCI quirk.

* mmc: sdhci: change sdhci-pltfm into a moduleShawn Guo2011-07-201-58/+24
| | | | | | | | | | | | | | | | | | | | | | | There are a couple of problems left from the sdhci pltfm and OF consolidation changes. * When building more than one sdhci-pltfm based drivers in the same image, linker will give multiple definition error on the sdhci-pltfm helper functions. For example right now, building sdhci-of-esdhc and sdhci-of-hlwd together is a valid combination from Kconfig view. * With the current build method, there is error with building the drivers as module, but module installation fails with modprobe. The patch fixes above problems by changing sdhci-pltfm into a module. To avoid EXPORT_SYMBOL on so many big endian IO accessors, it moves these accessors into sdhci-pltfm.h as the 'static inline' functions. As a result, sdhci.h needs to be included in sdhci-pltfm.h, and in turn can be removed from individual drivers which already include sdhci-pltfm.h.

* mmc: sdhci: make sdhci-of device drivers self registeredShawn Guo2011-07-201-1/+110
| | | | | | | | | | | | | | | | The patch turns the sdhci-of-core common stuff into helper functions added into sdhci-pltfm.c, and makes sdhci-of device drviers self registered using the same pair of .probe and .remove used by sdhci-pltfm device drivers. As a result, sdhci-of-core.c and sdhci-of.h can be eliminated with those common things merged into sdhci-pltfm.c and sdhci-pltfm.h respectively.

| | | | | | | | | | | | | | The patch turns the common stuff in sdhci-pltfm.c into functions, and add device drivers their own .probe and .remove which in turn call into the common functions, so that those sdhci-pltfm device drivers register itself and keep all device specific things away from common sdhci-pltfm file.
