2021-08-03ARM: dts: am57xx: Add PRUSS MDIO controller nodesSuman Anna1-0/+8
The PRUSSs on AM57xx SoCs contain an MDIO controller that can be used to control external PHYs associated with the Industrial Ethernet peripherals within each PRUSS. The MDIO module used within the PRU-ICSS is an instance of the MDIO Controller used in TI Davinci SoCs. The same bus frequency of 1 MHz is chosen as the regular MDIO node. The nodes are added in the common am57-pruss.dtsi file and enabled by default, but are disabled in all the existing AM57xx board dts files. These nodes need pinctrl lines, and so should be enabled only on boards where they are actually wired and pinned out for PRUSS Ethernet. Any new board dts file should disable these if they are not sure. Signed-off-by: Suman Anna <s-anna@ti.com> Signed-off-by: Andrew F. Davis <afd@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>
2020-09-10ARM: dts: am57xx-idk: switch to new cpsw switch drvGrygorii Strashko1-5/+0
Switch all am571/2/4-idk boards to use new cpsw switch driver. Those boards have 2 Ext. port wired and configured in dual_mac mode by default. Hence, dual_mac mode has been preserved the same way between legacy and new driver it's safe to switch drivers.

2020-07-13Replace HTTP links with HTTPS ones: OMAP DEVICE TREE SUPPORTAlexander A. Klimov1-1/+1
Rationale: Reduces attack surface on kernel devs opening the links for MITM as HTTPS traffic is much harder to manipulate. Deterministic algorithm: For each file: If not .svg: For each line: If doesn't contain `\bxmlns\b`: For each link, `\bhttp://[^# \t\r\n]*(?:\w|/)`: If neither `\bgnu\.org/license`, nor `\bmozilla\.org/MPL\b`: If both the HTTP and HTTPS versions return 200 OK and serve the same content: Replace HTTP with HTTPS.

2019-06-27ARM: dts: am57xx: Disable voltage switching for SD cardFaiz Abbas1-6/+1
If UHS speed modes are enabled, a compatible SD card switches down to 1.8V during enumeration. If after this a software reboot/crash takes place and on-chip ROM tries to enumerate the SD card, the difference in IO voltages (host @ 3.3V and card @ 1.8V) may end up damaging the card. The fix for this is to have support for power cycling the card in hardware (with a PORz/soft-reset line causing a power cycle of the card). Because the beaglebone X15 (rev A,B and C), am57xx-idks and am57xx-evms don't have this capability, disable voltage switching for these boards. The major effect of this is that the maximum supported speed mode is now high speed(50 MHz) down from SDR104(200 MHz). commit 88a748419b84 ("ARM: dts: am57xx-idk: Remove support for voltage switching for SD card") did this only for idk boards. Do it for all affected boards. Signed-off-by: Faiz Abbas <faiz_abbas@ti.com> Signed-off-by: Tony Lindgren <tony@atomide.com>

2019-04-12ARM: dts: dra7: Separate AM57 dtsi filesRoger Quadros1-3/+2
AM5 and DRA7 SoC families have different set of modules in them so the SoC sepecific dtsi files need to be separated. e.g. Some of the major differences between AM576 and DRA76 DRA76x AM576x USB3 x USB4 x ATL x VCP x MLB x ISS x PRU-ICSS1 x PRU-ICSS2 x This patch only deals with disabling USB3, USB4 and ATL for AM57 variants.

am574x-idk has no cpu vdd-supply at the moment. Hence hook smps12 regulator as cpu vdd-supply in am57xx-idk-common as the same regulator feeds on to cpu on am571/2/4-idks.

commit 18aa0f4bca701cb078a6 ("ARM: dts: am57xx-idk: Select pull down for mmc1_clk line in default mode") modified mmc1_pins_default pinctrl group in am57xx-idk-common.dtsi in order to change the CLK line to PIN_INPUT_PULLDOWN. However instead of modifying the pinctrl group, use the new pinctrl group "mmc1_pins_default_no_clk_pu" in dra7-mmc-iodelay.dtsi added specifically to be used for CLK line without external pull up.

2018-02-28ARM: dts: am57xx-idk: Select pull down for mmc1_clk line in default modeKishon Vijay Abraham I1-2/+1
During a short period when the bus voltage is switched from 3.3v to 1.8v, (to enumerate UHS mode), the mmc module is disabled and the mmc IO lines are kept in a state according to the programmed pad mux pull type. According to 4.2.4.2 Timing to Switch Signal Voltage in "SD Specifications Part 1 Physical Layer Specification Version 5.00 February 22, 2016", the host should hold CLK low for at least 5ms. In order to keep the card line low during voltage switch, the pad mux of mmc1_clk line should be configured to pull down. This is specific to am57xx-idk (and not all dra72/dra74 based boards) since mmc1_clk line in am57xx-idk is not connected to an external pullup. While at that change the order of header files in am571x-idk.dts and am572x-idk.dts so that the modified pinctrl values in am57xx-idk-common could take effect.
