This patch series updates/fixes below things: - Handle errors from tapdelay functions and return to set_delay() - Add ZynqMP firmware related enums which are used in sdhci driver - Replace mmio_write() with firmware call xilinx_pm_request() - Move tapdelay setting code from tap_delays.c to driver and remove tap_dealy.c and zynqmp_tap_delay.h - Change variable name from deviceid to node_id in couple of functions for consistancy - Add a workaround for sd card detect stable issue for Versal platforms - Use set_control_reg from sdhci.c
These patches are based on below microblaze U-Boot 'next' branch. https://source.denx.de/u-boot/custodians/u-boot-microblaze/-/commits/next
Changes in v4: - Rebase to latest u-boot-microblaze custodian 'next' branch - Initialized all enum pm_ioctl_id elements with explicit values
Changes in v3: - Added new line after return at two places - As we are seeing issues with SPL flow, keep zynqmp_mmio_write method to set tapdelay's and DLL resets. Add xilinx_pm_request on top of it for regular flow. - Changed the patch title to reflect these changes - Make the changes on top of patch 4/7 to move the code to zynq_sdhci.c
Changes in v2: - Split patch 1/7 to two patches, one for zynq_sdhci and other one for sdhci - This is the second patch that has been split from 1/7 - This covers changes for sdhci driver separately - Added a debug print in case of error from set_delay() - Added comment for why 1ms delay is needed between DLL assert and release - Remove mmc->dev->seq_ and use priv->deviceid instead - Changed return error from -EIO to -ETIMEDOUT in arasan_sdhci_probe() in card detect state stable workaround
