* mmc: sunxi: Honour non-removable property in DTAndre Przywara2019-01-291-1/+2
| | | | | | | | | | | | If a board DT describes a cd-gpios property, but also marks the storage as non-removable, we must ignore the GPIO (as Linux does). Teach the DM_MMC part of the Allwinner MMC driver about the non-removable DT property, to fix DM_MMC access on the SoPine and Pine64-LTS board.

* SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini2018-05-071-2/+1
| | | | | | | | | | | | | | | | | | | | When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
* sunxi: improve throughput in the sunxi_mmc driverPhilipp Tomsich2018-04-251-11/+16
| | | | | | | | | | | | | | | | | | | | | | Throughput tests have shown the sunxi_mmc driver to take over 10s to read 10MB from a fast eMMC device due to excessive delays in polling loops. This commit restructures the main polling loops to use get_timer(...) to determine whether a (millisecond) timeout has expired. We choose not to use the wait_bit function, as we don't need interruptability with ctrl-c and have at least one case where two bits (one for an error condition and another one for completion) need to be read and using wait_bit would have not added to the clarity. The observed speedup in testing on a A31 is greater than 10x (e.g. a 10MB write decreases from 9.302s to 0.884s).

* sunxi: mmc: Fix phase delaysStefan Mavrodiev2018-04-231-4/+4
| | | | | | | | | | | | | | | | | | | | | | | | U-boot driver for sunxi-mmc uses PLL6, unlike linux kernel where PLL5 is used, with clock rates respectively 600MHz and 768MHz. Thus there are different phase degree steps - 24 for the kernel and 30 for u-boot. In the kernel driver the phase is set 90 deg for output and 120 for sample. Dividing by 30 will result values 3 and 4. Those are the values set in the u-boot driver. However, the condition defining delays is wrong. MMC core driver requests clock of 52MHz, sunxi-driver sets clock of 50MHz, but phase is set 30 deg for output and 120 deg for sample. Apparently this works for most cards. On A20-SOM204-EVB-eMMC there is eMMC card (KLMAG2GEND) which complains about it. Maybe there is other boards with similar problem? So the fix is to match delays for both u-boot and kernel.

Note that this commit changes the behavior of the gmac and hdmi code for sun8i and the upcoming sun9i devices. This does not matter as sun8i does not have gmac nor hdmi, and sun9i has new hardware-blocks for these so the old code will not work there. Also this is intentional as if a sun8i / sun9i variant which does use the old hwblocks shows up then the GEN_SUN6I code paths will be the right ones to use. For completeness this also adds a SUNXI_GEN_SUN4I bool for A10/A13/A20. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Acked-by: Ian Campbell <ijc@hellion.org.uk>

| | | | | | | | | | | | It does not make sense to make gpio_direction_input() return the gpio input status. The return value of gpio_direction_input() is inconsistent if CONFIG_DM_GPIO is defined. And we don't need to call gpio_direction_input() int sunxi_mmc_getcd(). Just init the gpio once in mmc_resource_init() is enough.

* sunxi: mmc: Properly setup mod-clk and clock sampling phasesHans de Goede2015-01-141-27/+68
| | | | | | | | | | | | | | | | | | | | | | | The sunxi mmc controller has both an internal clock divider, as well as the divider in the mod0-clk for the mmc controller. The internal divider cannot be used, as it conflicts with the setting of clock sampling phases which is done in the mod0-clk, so it must be set to 0 (divide by 1). For some reason while the kernel has had this correct from day one, the u-boot sunxi mmc code has been using a fixed mod0-clk and setting its internal divider depending on the desired speed. This is something which we've inherited from the original Allwinner u-boot sources, but while this has been fixed in Allwinner's own u-boot code at least for the A23 and later upstream u-boot was still doing this wrong. This commit fixes this, thereby also fixing mmc support not working reliable on the A23 (which seems more sensitive to this) and possible also fixes some other sunxi mmc issues.
