2019-10-11arm: dra7xx: Hang on any failure during IOdelay recalibrationLokesh Vutla
If there is any failure during IOdelay recalibration sequence, IOs are not guaranteed to behave as expected. So hang on any failure during the sequence. Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
2019-10-11arm: dra7xx: Fix error path in iodelay recalibrationLokesh Vutla
When an error is reported in __recalibrate_iodelay_start(), de-isolation of IO doesn't happen. Because of this, undefined behaviour is observed on many peripherals without any error. So make sure io is out of isolation at the end of iodelay recalibration. Reported-by: Richard Woodruff <r-woodruff2@ti.com> Signed-off-by: Lokesh Vutla <lokeshvutla@ti.com>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
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>
2018-02-19ARM: OMAP5/DRA7: Enable iodelay recalibration to be done from ubootKishon Vijay Abraham I
Add a new API to perform iodelay recalibration without isolate io to be used in uboot. The data manual of J6/J6 Eco recommends to set different IODELAY values depending on the mode in which the MMC/SD is enumerated in order to ensure IO timings are met. The MMC driver can use the new API to set the IO delay values depending on the MMC mode. Signed-off-by: Kishon Vijay Abraham I <kishon@ti.com> Signed-off-by: Jean-Jacques Hiblot <jjhiblot@ti.com>
2016-11-21arm: Introduce arch/arm/mach-omap2 for OMAP2 derivative platformsTom Rini
This moves what was in arch/arm/cpu/armv7/omap-common in to arch/arm/mach-omap2 and moves arch/arm/cpu/armv7/{am33xx,omap3,omap4,omap5} in to arch/arm/mach-omap2 as subdirectories. All refernces to the former locations are updated to the current locations. For the logic to decide what our outputs are, consolidate the tests into a single config.mk rather than including 4.
