| * | mtd: cfi_mtd: Use DMA for readsVignesh Raghavendra2020-10-081-1/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When possible use DMA for reading from CFI flash, this provides upto 5x improvement in read performance with high speed CFI compliant flashes like HyperFlash. Code will gracefully fallback to CPU copy when DMA is unavailable. Signed-off-by: Vignesh Raghavendra <vigneshr@ti.com> Reviewed-by: Stefan Roese <sr@denx.de>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Octeon uses mapped addresses for virtual and physical memory. It's not that easy to calculate the resulting addresses here. So let's remove this BUG_ON() completely, as it's not really helpful. Please also note, that BUG_ON() is not recommended any more in the Linux kernel.

| * | pwm: Add driver for Amlogic Meson PWM controllerNeil Armstrong2020-10-053-0/+536
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds the driver for the PWM controller found in the Amlogic SoCs. This PWM is only a set of Gates, Dividers and Counters: PWM output is achieved by calculating a clock that permits calculating two periods (low and high). The counter then has to be set to switch after N cycles for the first half period. The hardware has no "polarity" setting. This driver reverses the period cycles (the low length is inverted with the high length) for PWM_POLARITY_INVERSED. Disabling the PWM stops the output immediately (without waiting for the current period to complete first). Signed-off-by: Neil Armstrong <narmstrong@baylibre.com>
