[ Upstream commit 00a39c92c8ab94727f021297d1748531af113fcd ]

DMTimers 13 - 16 are PWM capable and also can be used for CPTS input
signals generation. Hence, mark them as "ti,timer-pwm".

[ Upstream commit 27f13774654ea6bd0b6fc9b97cce8d19e5735661 ]

'dma-ranges' in a PCI bridge node does correctly set dma masks for PCI
devices not described in the DT. Certain DRA7 platforms (e.g., DRA76)
has RAM above 32-bit boundary (accessible with LPAE config) though the
PCIe bridge will be able to access only 32-bits. Add 'dma-ranges'
property in PCIe RC DT nodes to indicate the host bridge can access
only 32 bits.
