+/* Procedure of MT753x Internal Register Access
+ *
+ * 1. Internal Register Address
+ *
+ *    The MT753x has a 16-bit register address and each register is 32-bit.
+ *    This means the lowest two bits are not used as the register address is
+ *    4-byte aligned.
+ *
+ *    Rest of the valid bits are divided into two parts:
+ *      Bit 15..6 is the Page address
+ *      Bit 5..2 is the low address
+ *
+ *    -------------------------------------------------------------------
+ *    | 15  14  13  12  11  10   9   8   7   6 | 5   4   3   2 | 1   0  |
+ *    |----------------------------------------|---------------|--------|
+ *    |              Page Address              |    Address    | Unused |
+ *    -------------------------------------------------------------------
+ *
+ * 2. MDIO access timing
+ *
+ *    The MT753x uses the following MDIO timing for a single register read
+ *
+ *      Phase 1: Write Page Address
+ *    -------------------------------------------------------------------
+ *    | ST | OP | PHY_ADDR | TYPE | RSVD | TA |  RSVD |    PAGE_ADDR    |
+ *    -------------------------------------------------------------------
+ *    | 01 | 01 |   11111  |   1  | 1111 | xx | 00000 | REG_ADDR[15..6] |
+ *    -------------------------------------------------------------------
+ *
+ *      Phase 2: Write low Address & Read low word
+ *    -------------------------------------------------------------------
+ *    | ST | OP | PHY_ADDR | TYPE |    LOW_ADDR    | TA |      DATA     |
+ *    -------------------------------------------------------------------
+ *    | 01 | 10 |   11111  |   0  | REG_ADDR[5..2] | xx |  DATA[15..0]  |
+ *    -------------------------------------------------------------------
+ *
+ *      Phase 3: Read high word
+ *    -------------------------------------------------------------------
+ *    | ST | OP | PHY_ADDR | TYPE | RSVD | TA |           DATA          |
+ *    -------------------------------------------------------------------
+ *    | 01 | 10 |   11111  |   1  | 0000 | xx |       DATA[31..16]      |
+ *    -------------------------------------------------------------------
+ *
+ *    The MT753x uses the following MDIO timing for a single register write
+ *
+ *      Phase 1: Write Page Address (The same as read)
+ *
+ *      Phase 2: Write low Address and low word
+ *    -------------------------------------------------------------------
+ *    | ST | OP | PHY_ADDR | TYPE |    LOW_ADDR    | TA |      DATA     |
+ *    -------------------------------------------------------------------
+ *    | 01 | 01 |   11111  |   0  | REG_ADDR[5..2] | xx |  DATA[15..0]  |
+ *    -------------------------------------------------------------------
+ *
+ *      Phase 3: write high word
+ *    -------------------------------------------------------------------
+ *    | ST | OP | PHY_ADDR | TYPE | RSVD | TA |           DATA          |
+ *    -------------------------------------------------------------------
+ *    | 01 | 01 |   11111  |   1  | 0000 | xx |       DATA[31..16]      |
