ARM: OMAP: AM33XX: hwmod: Add hwmod data for debugSS
In the original hwmod data file, DebugSS entry was disabled, since we didn't (and do not) have SW to control it. This patch enables it back with right data, so that it can be controlled by different ways; and the suggested method it to have modular driver for debugSS as well. Refer to the link for more discussion on handling of debugSS - https://patchwork.kernel.org/patch/2212111/ Signed-off-by: Vaibhav Hiremath <hvaibhav@ti.com> Cc: Paul Walmsley <paul@pwsan.com> Cc: Tony Lindgren <tony@atomide.com> Signed-off-by: Paul Walmsley <paul@pwsan.com>
