[PATCH 0/6] i.MXRT1050 add Usb Host support
by Giulio Benetti 09 Jun '21

This patchset adds Usb Host support for imxrt1050-evk board adjusting the compatible driver ehci-mx6. This allows to read a FAT usb key connected to usbotg1 port of imxrt1050-evk board.

[PATCH 0/5] Fix i.MXRT1050 hang on lcdif init and improve DT for mxsfb
by Giulio Benetti 09 Jun '21

09 Jun '21

This patchset fixes u-boot hang on i.MXRT1050 while setting lcdif in mxsfb driver. There are 2 gates to be enabled to initialize mxsfb so let's introduce the missing gate as a clock and rename "per" clock to "pix" clock since in the other .dts files using *-lcdif "pix" is used. This patchset add also "disp_axi" clock enabling in mxsfb that should make able to every i.MX SoC with lcdif using DT. I didn't test it other than i.MXRT1050 since I don't have the boards. If someone can test it it would be great. Note that i.MX23/28 should fail using DT instead because they don't specify any clock-names in their dts.

[PATCH] arm: imx: imx8mm: clock: make debug output more descriptive
by Andrey Zhizhikin 09 Jun '21

09 Jun '21

Clock initialization functionality has ambitious debug messages, which are printed out when failures are triggered during execution: - Separate frequency table lookup functions have the the same output that makes it impossible to understand which function failed and produced the output - PLL decoding routine has a generic debug statement printed, which does not state the actual value failed to be found Extend the output for both cases with prefixing table lookup functions output with function name, and report the failed value in PLL decoding routine.

[PATCH 1/3] pci: Update the highest subordinate bus number for bridge setup

From: Masami Hiramatsu <masami.hiramatsu(a)linaro.org> Update the highest subordinate bus number after probing the devices under the bus for setting up the bridge correctly.

[PATCH] arm: imx: imx8mm: correct unrecognized fracpll frequency
by Andrey Zhizhikin 09 Jun '21

09 Jun '21

Frequency requested by ddrphy_init_set_dfi_clk from fracpll uses MHZ() macro, which expands the value provided to the Hz range without taking into account the precise Hz setting. This causes the frequency of 266 MHz not ot be found in the imx8mm_fracpll_tbl, since it is entered there with a precise Hz value. This in turn causes the boot hang in SPL, as proper DDR fracpll frequency cannot be determined. Correct the value in imx8mm_fracpll_tbl to match the one expanded by MHZ(266) macro, rounding it down to MHz range only.

[PATCH 1/3] ARM: dts: imxrt1050-evk: move all u-boot, dm-spl to imxrt1050-evk-u-boot.dtsi file
by Giulio Benetti 09 Jun '21

09 Jun '21

At the moment a lot of u-boot,dm-spl properties are present in board .dts file but this is not correct since u-boot,dm-spl property is u-boot specific and must be listed into the separate imrt1050-evk-u-boot.dtsi file. So let's move every u-boot,dm-spl property present in imxrt1050-evk.dts to imxrt1050-evk-u-boot.dtsi file.
