7 title: MMC Controller & Slots Common Properties
10 - Ulf Hansson <[email protected]>
13 These properties are common to multiple MMC host controllers and the
14 possible slots or ports for multi-slot controllers.
17 "#address-cells":
22 "#size-cells":
29 broken-cd:
32 There is no card detection available; polling must be used.
34 cd-gpios:
39 non-removable:
42 Non-removable slot (like eMMC); assume always present.

50 # inserted. Similar logic applies to the "wp-inverted" property.
53 # ways: as GPIOs, specified in cd-gpios and wp-gpios properties, or
55 # using *-inverted properties. GPIO polarity can also be specified
60 # respective *-inverted property property results in a
61 # double-inversion and actually means the "normal" line polarity is
63 wp-inverted:
68 cd-inverted:
75 bus-width:
82 max-frequency:
85 - for eMMC, the maximum supported frequency is 200MHz,
86 - for SD/SDIO cards the SDR104 mode has a max supported
88 - some mmc host controllers do support a max frequency upto
96 disable-wp:
99 When set, no physical write-protect line is present. This
101 dedicated write-protect detection logic. If a GPIO is always used
102 for the write-protect detection logic, it is sufficient to not
103 specify the wp-gpios property in the absence of a write-protect
106 wp-gpios:
109 GPIO to use for the write-protect detection.

122 cap-sd-highspeed:
125 SD high-speed timing is supported.
127 cap-mmc-highspeed:
130 MMC high-speed timing is supported.

182 mmc-ddr-1_2v:
185 eMMC high-speed DDR mode (1.2V I/O) is supported.
187 mmc-ddr-1_8v:
190 eMMC high-speed DDR mode (1.8V I/O) is supported.
192 mmc-ddr-3_3v:
195 eMMC high-speed DDR mode (3.3V I/O) is supported.

241 no-sd:
246 no-mmc:
249 Controller is limited to send MMC commands during
252 fixed-emmc-driver-type:
254 For non-removable eMMC, enforce this driver type. The value is
261 post-power-on-delay-ms:
263 It was invented for MMC pwrseq-simple which could be referred to
264 mmc-pwrseq-simple.yaml. But now it\'s reused as a tunable delay
266 regardless of whether pwrseq-simple is used. Default to 10ms if
267 no available.
270 supports-cqe:
274 MMC host controller supports HW command queue feature.
276 disable-cqe-dcmd:
279 The presence of this property indicates that the MMC
