2023-03-22PCI: imx6: Fix PERST# start-up sequenceFrancesco Dolcini
According to the PCIe standard the PERST# signal (reset-gpio in fsl,imx* compatible dts) should be kept asserted for at least 100 usec before the PCIe refclock is stable, should be kept asserted for at least 100 msec after the power rails are stable and the host should wait at least 100 msec after it is de-asserted before accessing the configuration space of any attached device. From PCIe CEM r2.0, sec 2.6.2 T-PVPERL: Power stable to PERST# inactive - 100 msec T-PERST-CLK: REFCLK stable before PERST# inactive - 100 usec. From PCIe r5.0, sec 6.6.1 With a Downstream Port that does not support Link speeds greater than 5.0 GT/s, software must wait a minimum of 100 ms before sending a Configuration Request to the device immediately below that Port. Failure to do so could prevent PCIe devices to be working correctly, and this was experienced with real devices. Move reset assert to imx6_pcie_assert_core_reset(), this way we ensure that PERST# is asserted before enabling any clock, move de-assert to the end of imx6_pcie_deassert_core_reset() after the clock is enabled and deemed stable and add a new delay of 100 msec just afterward.

2023-03-21drm/imx: imx8mp-ldb: fix check on LDB valid clockRafael Beims
Remove wrong mode-fixup on the LDB driver that limited the pixel clocks to 74.25MHz in single channel mode and 148.5MHz in dual channel mode. According to the iMX8MP Reference manual, the LDB peripheral supports: " - Single channel (4 lanes) output at up to 80MHz pixel clock and LVDS clock. This supports resolutions up to 1366x768p60. - Dual asynchronous channels (8 data, 2 clocks). This is intended for a single panel with two interfaces, transferring across two channels (even pixel/odd pixel). This is supported at up to 160MHz pixel clock, which is up to 80MHz LVDS clock (due to 2 pixels per LVDS clock). This supports resolutions above 1366x768p60, up to 1080p60. " We contacted NXP trying to find the real reason for this seemingly random limitation, but we didn't get any response. The forced pixel clock values were removed and now it's possible to drive LVDS displays that have pixel clock requirements out of the previously limited range, but that are still within the hardware limitations. A check was added to ensure that clocks out of range are denied. With this change, it is now possible to use this display: - LVDS display (CMT1210A07R00 800x600 - 40MHz pixel clock) Also, the Toradex 10" Capacitive touch display (68.93MHz pixel clock) continues to work.

2023-03-21clk: imx: pll14xx: Support dynamic ratesSascha Hauer
The pll1443x PLL so far only supports rates from a rate table passed during initialization. Calculating PLL settings dynamically helps audio applications to get their desired rates, so support for this is added in this patch. The strategy to get to the PLL setting for a rate is: - First try to only adjust kdiv which specifies the fractional part of the PLL. This setting can be changed without glitches on the output and is therefore preferred - When that isn't possible then the rate table is searched for suitable rates, so for standard rates the same settings are used as without this patch - As a last resort the best settings are calculated dynamically The code in this patch is based on patches from Adrian Alonso <adrian.alonso@nxp.com> and Mads Bligaard Nielsen <bli@bang-olufsen.dk> Upstream-Status: Backport [b09c68dc57c9d44071d83bb935b733f53ea2b2b4] Signed-off-by: Sascha Hauer <s.hauer@pengutronix.de> Reviewed-by: Abel Vesa <abel.vesa@nxp.com> Link: https://lore.kernel.org/r/20220304125256.2125023-9-s.hauer@pengutronix.de Signed-off-by: Abel Vesa <abel.vesa@nxp.com> Signed-off-by: Rafael Beims <rafael.beims@toradex.com>

2023-03-15arm64: dts: colibri-imx8x: Add reserved memoryPhilippe Schenker
Use the reserved-memory nodes from MEK with two adjustments: - Out of the history from 5.4-2.3.x-imx delete CMA node - Delete DSP nodes, since we only use SoCs without DSP Upstream-Status: Pending - There is currently no need for this in upstream linux Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>
2023-03-15arm64: dts: colibri-imx8x: Add analogue inputsPhilippe Schenker
This commit does forward-port the ADC functionality from toradex_5.4-2.3.x-imx. Upstream-Status: Pending ADC support seems to be available in mainline, "nxp,imx8qxp-adc" compatible and node defined in "imx8-ss-dma.dtsi". However it was not possible to have it working on mainline so we postponed this for the moment. Signed-off-by: Philippe Schenker <philippe.schenker@toradex.com>

2023-03-14arm64: dts: colibri-imx8x: Move gpio-keys to som levelPhilippe Schenker
SODIMM_45 that is connected to "&lsio_gpio3 10" is defined in the Colibri standard to be a wakeup pin. Move this to the SoM level device-tree and keep it disabled by default but do enable it again on the carrier-board.

2023-03-14arm64: dts: colibri-imx8x: Add no-1-8-v to sd-cardPhilippe Schenker
Many Colibri carrier boards are using 3.3V pull-up resistors on the SD-Card connector. Letting it switch to 1.8V is an invalid state. Do prevent this from happening by keeping the signaling voltage at 3.3V.
