We can now probe devices with ti-sysc interconnect driver and dts data. Let's drop the related platform data and custom ti,hwmods dts property. As we're just dropping data, and the early platform data init is based on the custom ti,hwmods property, we want to drop both the platform data and ti,hwmods property in a single patch.

Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

The watchdog timers have been added for the IPU and DSP remoteproc devices for the OMAP5 uEVM board. The following timers (same as the timers on OMAP4 Panda boards) are used as the watchdog timers, DSP : GPT6 IPU : GPT9 & GPT11 (one for each Cortex-M4 core) The MPU-side drivers will use this data to initialize the watchdog timers, and listen for any watchdog triggers. The BIOS-side code needs to configure and refresh these timers properly to not throw a watchdog error. These timers can be changed or removed as per the system integration needs, alongside appropriate equivalent changes on the firmware side. Signed-off-by:Suman Anna <s-anna@ti.com> Signed-off-by:

The BIOS System Tick timers have been added for the IPU and DSP remoteproc devices for the OMAP5 uEVM boards. The following timers (same as the timers on OMAP4 Panda boards) are chosen: IPU : GPT3 (SMP-mode) DSP : GPT5 IPU has two Cortex-M4 processors, and is currently expected to be running in SMP-mode, so only a single timer suffices to provide the BIOS tick timer. An additional timer should be added for the second processor in IPU if it were to be run in non-SMP mode. The timer value also needs to be unique from the ones used by other processors so that they can be run simultaneously. The timers are optional, but are mandatory to support device management features such as power management and watchdog support. The above are added to successfully boot and execute firmware images configured with the respective timers, images that use internal processor subsystem timers are not affected. The timers can be changed or removed as per the system integration needs, alongside equivalent changes on the firmware side. Signed-off-by: -

The CMA reserved memory nodes have been added for the IPU and DSP remoteproc devices on the OMAP5 uEVM board. These nodes are assigned to the respective rproc device nodes, and both the IPU and DSP remote processors are enabled for this board. The current CMA pools and sizes are defined statically for each device. The starting addresses are fixed to meet current dependencies on the remote processor firmwares, and will go away when the remote-side code has been improved to gather this information runtime during its initialization. An associated pair of the rproc node and its CMA node can be disabled later on if there is no use-case defined to use that remote processor. Signed-off-by:

OMAP5, like OMAP4, also has two remote processor subsystems, DSP and IPU. The IPU subsystem though has dual Cortex-M4 processors instead of the dual Cortex-M3 processors in OMAP4, but otherwise has almost the same set of features. Add the DT nodes for these two processor sub-systems for all OMAP5 SoCs. The nodes have the 'iommus', 'clocks', 'resets', 'firmware' and 'mboxes' properties added, and are disabled for now. The IPU node has its L2 RAM memory specified through the 'reg' and 'reg-names' properties. The DSP node doesn't have these since it doesn't have any L2 RAM memories, but has an additional 'ti,bootreg' property instead as it has a specific boot register that needs to be programmed for booting. These nodes should be enabled as per the individual product configuration in the corresponding board dts files. Signed-off-by:

The compatible property for the DSP node is updated to match the OMAP remoteproc bindings. The node is moved from the soc node to the ocp node to better reflect the connectivity from MPU side. The node is updated with the 'ti,bootreg', 'clocks', 'resets', 'iommus', 'mboxes' and 'firmware' properties. Note that the node does not have any 'reg' or 'reg-names' properties since it doesn't have any L2 RAM memory, but only Unicaches. The node is disabled for now, and should be enabled as per the individual product configuration in the corresponding board dts files. Signed-off-by:

The commit d41e5304 ("clk: ti: omap5: cleanup unnecessary clock aliases") has cleaned up all timer_sys_ck clock aliases and retained only the timer_32k_ck clock alias. The OMAP clocksource timer driver though still uses this clock alias when reconfiguring the parent clock source for the timer functional clocks, so add these clocks to all the timer nodes except for the always-on timers 1 and 12. This is required by the OMAP remoteproc driver to successfully acquire a timer and configure the source clock to be driven from timer_sys_ck clock. Signed-off-by:

These pins on the PocketBeagle P1 and P2 headers are connected to AM3358 balls with gpio lines, and these pins are not used for any other peripherals by default. These GPIO lines are unclaimed and could be used by userspace program through the gpiod ABI. This patch adds a "default" state in the am33xx_pinmux node and sets the mux for those pins to gpio (mode 7) and input enable. The "pinctrl-single,bias-pullup" and "pinctrl-single,bias-pulldown" pinconf properties are also set for each pin per the ball reset state in section 4.2 of the datasheet [0].
