Andrew spotted an issue on patch 16/17 and I'm going to submit a patch fixing that. Please either squash it or apply it separately at your own convenience. - Mani > -- > Martin K.

I was told that SoCs based on UFS 1.x controllers were not widely used in production, though I don't know why. - Mani > Konrad

Hello, This series has code some cleanups to the Qcom UFS driver. No functional change. In this version, I've removed code supporting legacy controllers ver < 2.0, as the respective platforms were never supported in upstream. Tested on: RB5 development board based on Qcom SM8250 SoC. - Mani Changes in v2: * Collected review tags * Fixed the comments from Andrew * Added a few more patches, most notably one removing the code for old controllers (ver < v2.0) Manivannan Sadhasivam (17): scsi: ufs: qcom: Use clk_bulk APIs for managing lane clocks scsi: ufs: qcom: Fix the return value of ufs_qcom_ice_program_key() scsi: ufs: qcom: Fix the return value when platform_get_resource_byname() fails scsi: ufs: qcom: Remove superfluous variable assignments scsi: ufs: qcom: Remove the warning message when core_reset is not available scsi: ufs: qcom: Export ufshcd_{enable/disable}_irq helpers and make use of them scsi: ufs: qcom: Fail ufs_qcom_power_up_sequence() when core_reset fails scsi: ufs: qcom: Check the return value of ufs_qcom_power_up_sequence() scsi: ufs: qcom: Remove redundant error print for devm_kzalloc() failure scsi: ufs: qcom: Use dev_err_probe() to simplify error handling of devm_gpiod_get_optional() scsi: ufs: qcom: Remove unused ufs_qcom_hosts struct array scsi: ufs: qcom: Sort includes alphabetically scsi: ufs: qcom: Initialize cycles_in_1us variable in ufs_qcom_set_core_clk_ctrl() scsi: ufs: qcom: Simplify ufs_qcom_{assert/deassert}_reset scsi: ufs: qcom: Remove support for host controllers older than v2.0 scsi: ufs: qcom: Use ufshcd_rmwl() where applicable scsi: ufs: qcom: Remove unused definitions drivers/ufs/core/ufshcd.c | 6 +- drivers/ufs/host/ufs-qcom.c | 377 +++++------------------------------- drivers/ufs/host/ufs-qcom.h | 52 +---- include/ufs/ufshcd.h | 2 + 4 files changed, 66 insertions(+), 371 deletions(-)
