mmc: remove sirf prima/atlas driver

2021-02-01T10:54:49+00:00

The CSR SiRF prima2/atlas platforms are getting removed, so this driver is no longer needed. Cc: Barry Song Signed-off-by: Arnd Bergmann Acked-by: Barry Song Link: https://lore.kernel.org/r/20210120142801.334550-3-arnd@kernel.org Signed-off-by: Ulf Hansson

mmc: Set PROBE_PREFER_ASYNCHRONOUS for drivers that existed in v4.4

2020-09-07T12:20:17+00:00

This is like commit 3d3451124f3d ("mmc: sdhci-msm: Prefer asynchronous probe") but applied to a whole pile of drivers. This batch converts the drivers that appeared to be around in the v4.4 timeframe.

mmc: core: Remove mmc_gpiod_request_*(invert_gpio)

Now that invert_gpio arguments are unused, let's remove them. Signed-off-by: Michał Mirosław Link: https://lore.kernel.org/r/64d766d1f8af2e22bce32f4ffa453f7234207ad6.1576031637.git.mirq-linux@rere.qmqm.pl Signed-off-by: Ulf Hansson

treewide: Replace GPLv2 boilerplate/reference with SPDX - rule 4

Based on 1 normalized pattern(s): licensed under gplv2 or later extracted by the scancode license scanner the SPDX license identifier GPL-2.0-or-later has been chosen to replace the boilerplate/reference in 118 file(s).

mmc: sdhci: sirf: Use the slot GPIO descriptor

2018-10-08T09:40:43+00:00

This driver is complicating things for no reason: the "cd" GPIO can easily be retrieved from the device tree if present using just mmc_gpiod_request_cd(), which will fetch the descriptor from the device tree using the standard binding just fine. If the retrieveal is successful, we also request the IRQ. As a result the private subdriver data can be removed entirely.

mmc: sdhci: enable/disable the clock in sdhci_pltfm_suspend/resume

2017-08-30T13:03:44+00:00

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 Acked-by: Adrian Hunter Acked-by: Al Cooper Signed-off-by: Ulf Hansson

mmc: sdhci-sirf: constify sdhci_pltfm_data and sdhci_ops structures

2017-08-30T12:01:52+00:00

The sdhci_pltfm_data structure is only passed as the second argument of sdhci_pltfm_init, which is const, while the sdhci_ops structure is only stored in the ops field of a sdhci_pltfm_data structure, which is also const. Thus both kinds of structures can be const as well. Done with the help of Coccinelle. Signed-off-by: Julia Lawall Signed-off-by: Ulf Hansson

mmc: sdhci: Let drivers decide whether to use mmc_retune_needed() with pm

2017-04-24T19:41:26+00:00

Devices might save and restore tuning values so that re-tuning might not be needed after a pm transition. Let drivers decide by pushing the mmc_retune_needed() logic down to them. Signed-off-by: Adrian Hunter Signed-off-by: Ulf Hansson Tested-by: Ludovic Desroches

mmc: sdhci-sirf: Remove non needed #ifdef CONFIG_PM* for dev_pm_ops

2016-07-27T09:25:23+00:00

The SIMPLE_DEV_PM_OPS macro deals with the CONFIG_PM options when assigning the PM callbacks, thus it's not needed to control this when using the macro. By removing the non needed #ifdef, the code becomes a bit cleaner. Signed-off-by: Ulf Hansson

mmc: mmc: extend the mmc_send_tuning()

2015-10-27T09:38:41+00:00

The mmc_execute_tuning() has already prepared the opcode, there is no need to prepare it again at mmc_send_tuning(), and, there is a BUG of mmc_send_tuning() to determine the opcode by bus width, assume eMMC was running at HS200, 4bit mode, then the mmc_send_tuning() will overwrite the opcode from CMD21 to CMD19, then got error. in addition, extend an argument of "cmd_error" to allow getting if there was cmd error when tune response.
