mmc: mvsdio: Use sg_miter for PIO

2024-02-13T12:40:56Z

Use the scatterlist memory iterator instead of just dereferencing virtual memory using sg_virt(). This make highmem references work properly. This driver also has a bug in the PIO sglist handling that is fixed as part of the patch: it does not travers the list of scatterbuffers: it will just process the first item in the list. This is fixed by augmenting the logic such that we do not process more than one sgitem per IRQ instead of counting down potentially the whole length of the request. We can suspect that the PIO path is quite untested.

mmc: mvsdio: Convert to platform remove callback returning void

2023-08-15T10:48:20Z

The .remove() callback for a platform driver returns an int which makes many driver authors wrongly assume it's possible to do error handling by returning an error code. However the value returned is (mostly) ignored and this typically results in resource leaks. To improve here there is a quest to make the remove callback return void. In the first step of this quest all drivers are converted to .remove_new() which already returns void. Trivially convert this driver from always returning zero in the remove callback to the void returning variant.

mmc: mvsdio: fix deferred probing

2023-06-19T11:31:12Z

The driver overrides the error codes returned by platform_get_irq() to -ENXIO, so if it returns -EPROBE_DEFER, the driver will fail the probe permanently instead of the deferred probing. Switch to propagating the error codes upstream.

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

2020-09-07T12:20:17Z

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: host: Drop redundant MMC_CAP_ERASE

2020-05-28T09:22:14Z

The MMC_CAP_ERASE bit is no longer used by the mmc core as erase, discard and trim operations are now always supported. Therefore, drop the bit and move all mmc hosts away from using it.

There is no obvious reasons to why mvsdio shouldn't be able to support erase/trim/discard operations, hence let's set MMC_CAP_ERASE for it. Cc: Damien Thebault Signed-off-by: Ulf Hansson Tested-by: Damien Thebault
