V2:
- Only do array allocation when num_supplies > 0 - Bjorn
- Set unused regulators to {} instead of { NULL } - Bjorn
Bootable and testable tree for both RB3 and RB5 here:

V1:
Following on from comments from Vladimir on the sm8250 CAMSS patches I had
a look through the RB3 and RB5 schematics.
Here we see the CSI PHY connects to the same VDDA power-rails as USB, PCIe,
UFS and the DSI PHYs.
Right now CAMSS works on SDM845 and SM8250 because one of the USB, PCIe,
or UFS has enabled the relevant VDDA supplies, prior to the CAMSS driver
running.
The solution is to
- Fix the describing YAML
- Add in regulator_bulk_enable()/regulator_bulk_disable()
- Update the DTS to point at the necessary regulators
I have an SDM660 board on-order so when it arrives I can also look into the
vdda_sec regulator if nobody else has.
For now this series addresses the fundamental gap in the CSI PHY power
rails and remediates the situation for the two boards I have schematics for
and can test, RB3/SDM845 and RB5/SM8250.
This patch applies on top of
git.linuxtv.org/hverkuil/media_tree.git / br-v5.17j

If we review the schematic for RB3 Thundercomm document Turbox-845 we see
that the CAMSS CSI PHY has the same basic power-rail layout as UFS, PCIe
and USB PHYs.
We should therefore have two regulator declarations as is the case for UFS,
PCIe and USB.

Add in missing vdda-phy-supply and vdda-pll-supply declarations. The
sm8250 USB, PCIe, UFS, DSI and CSI PHYs use a common set of vdda rails.
Define the CSI vdda regulators in the same way the qmp PHY does.

The dts entry vdda-supply connects to a common vdda-phy-supply rail. Rename
to reflect what the functionality is.

Add the ability to enable or disable multiple regulators in bulk with
camss. This is useful for sm8250, sdm845 and it looks like sdm660 where we
have more than one CSI regulator to do at once.
It should just work for standalone existing vdda regulators and parts which
don't have an explicitly defined CSI regulator.

Reviewing the RB3 schematic its clear that we have missed out on defining
one of the power-rails associated with the CSI PHY.
Other PHYs such as the UFS, PCIe and USB connect to these rails and define
each regulator individually.
This means if we were to switch off the other various PHYs which enable
these rails, the CAMSS would not appropriately power-on the CSI PHY.

res->regulators is declared as
char *regulators[CAMSS_RES_MAX];
which means ARRAY_SIZE(regulators) == CAMSS_RES_MAX
I could do something like this
struct resources {
- char *regulator[CAMSS_RES_MAX];
+ char **regulators;
char *clock[CAMSS_RES_MAX];
u32 clock_rate[CAMSS_RES_MAX][CAMSS_RES_MAX];
char *reg[CAMSS_RES_MAX];
+static const char const *csid_res_8x16_regulators = { "vdda" };
static const struct resources csid_res_8x16[] = {
/* CSID0 */
{
- .regulator = { "vdda" },
+ .regulators = csid_res_8x16_regulators,
static const struct resources vfe_res_8x16[] = {
/* VFE0 */
{
- .regulator = {},
+ .regulators = NULL,
then the ARRAY_SIZE() thing would work
If that change is made - then it would also make sense to change up
*clock[CAMSS_RES_MAX]; *reg[CAMSS_RES_MAX]..

np, I'll leave this change as part of this set anyway
