* scsi: ufs: qcom: Update MODE_MAX cfg_bw valueManish Pandey2024-10-041-1/+1
| | | | | | | | | | | | | | | | | | commit 0c40f079f1c808e7e480c795a79009f200366eb1 upstream. Commit 8db8f6ce556a ("scsi: ufs: qcom: Add missing interconnect bandwidth values for Gear 5") updated the ufs_qcom_bw_table for Gear 5. However, it missed updating the cfg_bw value for the max mode. Hence update the cfg_bw value for the max mode for UFS 4.x devices.

It was send previously in [1] and [2] but included the other clock, phy and DTS parts. This series has been split into just the ufs-exynos part to hopefully make things easier. With this series, plus the phy, clock and dts changes UFS is functional upstream for Pixel 6. The SKhynix HN8T05BZGKX015 can be enumerated, partitions mounted etc. The series is split into some prepatory patches for ufs-exynos and a final patch that adds the gs101 support. Note the sysreg clock has been moved to ufs node as fine grained clock control around the syscon sysreg register accesses doesn't result in functional UFS. regards, Peter Link: https://lore.kernel.org/r/20240426122004.2249178-1-peter.griffin@linaro.org Signed-off-by: Martin K.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add a dedicated compatible and drv_data with associated hooks for gs101 SoC found on Pixel 6.

EXYNOS_UFS_OPT_TIMER_TICK_SELECT option is also set to select tick source. This has been done so as not to effect any existing platforms. DBG_OPTION_SUITE on gs101 has different address offsets to other SoCs so these register offsets now come from uic_attr struct.

| |/ / | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | UFS spec version 2.1 was published more than 10 years ago. It is vanishingly unlikely that even there are out there platforms that uses earlier host controllers, let alone that those ancient platforms will ever run a V6.10 kernel. To be extra cautious, leave out removal of UFSHCI 2.0 support from this patch, and just remove support of host controllers prior to UFS2.0. This patch removes some legacy tuning calls that no longer apply.

UFS has a lot of mb() variants used, most with comments saying "ensure this takes effect before continuing". mb()'s aren't really the way to guarantee that, a read back is the best method. Some of these though I think could go a step further and remove the mb() variant without a read back. As far as I can tell there's no real reason to ensure it takes effect in most cases (there's no delay() or anything afterwards, and eventually another readl()/writel() happens which is by definition ordered). Some of the patches in this series do that if I was confident it was safe (or a reviewer pointed out prior that they thought it was safe to do so).

The REINIT quirk only applies starting with controller v4. For these, ufs_qcom_get_hs_gear() reads the highest supported gear when setting the host_params. After the negotiation, if the host and device are on the same gear, it is the highest gear supported between the two. Skip REINIT to save some time.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The comments that currently are within the hw_ver < 4 conditional are misleading. They really apply to various branches of the conditionals there and incorrectly state that the phy_gear value can increase. Right now the logic is to: - Default to max supported gear for phy_gear - Set phy_gear to minimum value if version < 4 since those versions only support one PHY init sequence (and therefore don't need reinit) - Set phy_gear to the optimal value if the device version is already populated in the controller registers on boot Let's move some of the comment to outside the if statement and clean up the bit left about switching to a higher gear on reinit. This way the comment more accurately reflects the logic.
