+STMicroelectronics STM32 Peripheral Reset Clock Controller
+==========================================================

+- #clock-cells: 1, device nodes should specify the clock in their

+- #reset-cells: Shall be 1

+
+Specifying clocks
+=================
+
+All available clocks are defined as preprocessor macros in
+dt-bindings/clock/stm32mp1-clks.h header and can be used in device
+tree sources.
+
+Specifying softreset control of devices
+=======================================
+
+Device nodes should specify the reset channel required in their "resets"
+property, containing a phandle to the reset device node and an index specifying
+which channel to use.
+The index is the bit number within the RCC registers bank, starting from RCC
+base address.
+It is calculated as: index = register_offset / 4 * 32 + bit_offset.
+Where bit_offset is the bit offset within the register.
+
+For example on STM32MP1, for LTDC reset:
+ ltdc = APB4_RSTSETR_offset / 4 * 32 + LTDC_bit_offset
+      = 0x180 / 4 * 32 + 0 = 3072
+
+The list of valid indices for STM32MP1 is available in:
+include/dt-bindings/reset-controller/stm32mp1-resets.h
+
+This file implements defines like:

+Binding for TI DaVinci Power Sleep Controller (PSC)
+
+The PSC provides power management, clock gating and reset functionality. It is
+primarily used for clocking.
+
+Required properties:
+- compatible: shall be one of:
+	- "ti,da850-psc0" for PSC0 on DA850/OMAP-L138/AM18XX
+	- "ti,da850-psc1" for PSC1 on DA850/OMAP-L138/AM18XX
+- reg: physical base address and size of the controller's register area
+- #clock-cells: from common clock binding; shall be set to 1
+- #power-domain-cells: from generic power domain binding; shall be set to 1.
+- clocks: phandles to clocks corresponding to the clock-names property
+- clock-names: list of parent clock names - depends on compatible value
+	- for "ti,da850-psc0", shall be "pll0_sysclk1", "pll0_sysclk2",
+	  "pll0_sysclk4", "pll0_sysclk6", "async1"
+	- for "ti,da850-psc1", shall be "pll0_sysclk2", "pll0_sysclk4", "async3"
+
+Optional properties:
+- #reset-cells: from reset binding; shall be set to 1 - only applicable when
+  at least one local domain provides a local reset.
+
+Consumers:
+
+	Clock, power domain and reset consumers shall use the local power domain
+	module ID (LPSC) as the index corresponding to the clock cell. Refer to
+	the device-specific datasheet to find these numbers. NB: Most local
+	domains	only provide a clock/power domain and not a reset.
+
+Examples:
+
+	psc0: clock-controller@10000 {
+		compatible = "ti,da850-psc0";

-       for details.  YYERROR is fine as it does not invoke this
-       function.
-     - If this state is a consistent state with a default action, then
-       the only way this function was invoked is if the default action
-       is an error action.  In that case, don't check for expected
-       tokens because there are none.
-     - The only way there can be no lookahead present (in yychar) is if
-       this state is a consistent state with a default action.  Thus,
-       detecting the absence of a lookahead is sufficient to determine
-       that there is no unexpected or expected token to report.  In that
-       case, just report a simple "syntax error".
-     - Don't assume there isn't a lookahead just because this state is a
-       consistent state with a default action.  There might have been a
-       previous inconsistent state, consistent state with a non-default
-       action, or user semantic action that manipulated yychar.
-     - Of course, the expected token list depends on states to have
-       correct lookahead information, and it depends on the parser not
-       to perform extra reductions after fetching a lookahead from the
-       scanner and before detecting a syntax error.  Thus, state merging
-       (from LALR or IELR) and default reductions corrupt the expected
-       token list.  However, the list is correct for canonical LR with
-       one exception: it will still contain any token that will not be
-       accepted due to an error action in a later state.

+Package: $dbg_packagename
+Section: debug
+Architecture: $debarch
+Description: Linux kernel debugging symbols for $version
+ This package will come in handy if you need to debug the kernel. It provides
+ all the necessary debug symbols for the kernel and its modules.
