2019-04-05bus: ti-sysc: Pass clockactivity quirk to platform functionsTony Lindgren
We already have the clockactivity quirk set for some modules like i2c, timers and smartreflex. But we're not passing it to the platform functions yet. Let's start doing that in preparation of dropping interconnect target module platform data in favor of device tree based data. Signed-off-by: Tony Lindgren <tony@atomide.com>

2019-04-04ARM: dts: sunxi: Remove useless pinctrl nodesMaxime Ripard
We have for the H3 boards some kind of cargo cult apparently, where we would have a pinctrl node even for GPIOs without any particular settings. This is pretty much useless, so let's remove them.

So far we've enabled pull-up and pull-down resistors on GPIOs using a pinctrl node. Now that the GPIO binding allows for a flag to declare this, let's switch to it.

2019-04-03bus: ti-sysc: Add quirk handling for external optional functional clockTony Lindgren
We cannot access mcpdm registers at all unless there is an optional pdmclk configured. As this is currently only needed for mcpdm, let's check for mcpdm in sysc_get_clocks(). If it turns out to be needed for other modules too, we can add more flags to the quirks table for this. Signed-off-by: Tony Lindgren <tony@atomide.com>
2019-04-03bus: ti-sysc: Add support for early quirks based on register addressTony Lindgren
At least mcpdm needs an optional external clock enabled to function and this clock typically comes from the PMIC. We can detect mcpdm based on the interconnect target module address and set a quirk flag early. To do this, let's initialize the clocks a bit later and add a new function for sysc_init_early_quirks(). Note that we cannot yet enable the early quirks for mcpdm until the optional external clocks are handled in the in the following patch. Signed-off-by: Tony Lindgren <tony@atomide.com>
2019-04-03bus: ti-sysc: Move rstctrl reset to happen laterTony Lindgren
We can do the rsstctrl a bit later, but need to deassert rstctrl reset before the clocks are enabled if asserted. Let's only init restctrl in sysc_init_resets() and do the reset later on just before we enable the device clocks. Signed-off-by: Tony Lindgren <tony@atomide.com>
2019-04-03bus: ti-sysc: Manage clocks for the interconnect target module in all casesTony Lindgren
We are currently not managing interconnect target module clocks in the for legacy platform data based case. This causes a problem for using the platform data based functions when dropping the platform data for the interconnect target module configuration. To avoid a situation where we need to populate the main and optional clocks also for the platform data based functions, let's just manage the clocks directly in ti-sysc driver. This means that until the interconnect target module confugration platform data is dropped our use count for clk_enable() will be 2 instead of 1. Signed-off-by: Tony Lindgren <tony@atomide.com>
2019-04-03bus: ti-sysc: Allocate mdata as needed and do platform data based init laterTony Lindgren
The platform data based init functions typically reset the interconnect target module configure the registers. As we may need the interconnect target module specific quirks configured based on the revision register, we want to move the platform data based init to happen later. Let's allocate mdata as needed so it's available for sysc_legacy_init() that we call with module clocks enabled from sysc_init_module(). Signed-off-by: Tony Lindgren <tony@atomide.com>
2019-04-03bus: ti-sysc: Enable all clocks directly during init to read revisionTony Lindgren
The first thing we want to do is just read the module revision register to be able to configure the module specific quirks and configure the module registers. As the interconnect target module may not yet be properly configured and may need a reset first, we don't want to use pm_runtime_get() at this point. To read the revision register, let's just enable the all the clocks for the interconnect target module during init even if the optional clocks are not needed. That way we can read the revision register to configure the quirks needed for PM runtime. Signed-off-by: Tony Lindgren <tony@atomide.com>

Remove the bindings ID of the clock input of the controller. These clocks are purely internal to the controller, exposing them was a mistake. Actually, these should not even be in the provider and have IDs to begin with. Unexpose these IDs before: * someone starts using them (even if there no valid reason to do so) * the actual clocks are removed. The fact that they exist is just the result of an ugly hack.
