MLK-21865 Revert "regmap: use debugfs even when no device" This reverts commit 9b947a13e7f6017f18470f665992dbae267852b3. The commit 9b947a13e7f6017f18470f665992dbae267852b3 does not consider power and clock when expose the regmap into debugsfs. This may bring some problem for some case. E.g., For reset registers (not real GPR, but csi bridge register) for MIPI DSI, MIPI CSI and LCDIF on i.mx8mm, they only can be accessed after the disp_root clock and dispmix power has been turned on, otherwise the system may be stuck. on i.mx8mm evk, the command to reproduce (with default dtb, no display/capture running): cat /sys/kernel/debug/regmap/dummy-display-gpr@32e28000/registers This patch reverted previous commit to avoid the exposure.
