SVD for s32k344 leads to uncompilable output due to many duplicated methods

Hi!

I'm new to embedded rust, and I probably just don't understand the cli options to svd2rust and how to get working output.

An example from the SVD I'm using that leads to many duplicated functions:

<field>
<name>RR_INITMOD</name>
<description>Initialization Delay Modulus</description>
<bitOffset>16</bitOffset>
<bitWidth>6</bitWidth>
<access>read-write</access>
<enumeratedValues>
  <enumeratedValue>
    <name>MOD_63</name>
    <description>63 cycles (same as 111111b)</description>
    <value>0</value>
  </enumeratedValue>
  <enumeratedValue>
    <name>MOD_1_63</name>
    <description>1 to 63 cycles</description>
    <value>0x1</value>
  </enumeratedValue>
  <enumeratedValue>
    <name>MOD_1_63</name>
    <description>1 to 63 cycles</description>
    <value>0x2</value>
  </enumeratedValue>
  <enumeratedValue>
    <name>MOD_1_63</name>
    <description>1 to 63 cycles</description>
    <value>0x3</value>
  </enumeratedValue>
  <enumeratedValue>
    <name>MOD_1_63</name>
    <description>1 to 63 cycles</description>
    <value>0x4</value>
  </enumeratedValue>
  <enumeratedValue>
    <name>MOD_1_63</name>
    <description>1 to 63 cycles</description>
    <value>0x5</value>
  </enumeratedValue>
  <enumeratedValue>
    <name>MOD_1_63</name>
    <description>1 to 63 cycles</description>
    <value>0x6</value>
  </enumeratedValue>
  <enumeratedValue>
    <name>MOD_1_63</name>
    <description>1 to 63 cycles</description>
    <value>0x7</value>
  </enumeratedValue>
  <enumeratedValue>
    <name>MOD_1_63</name>
    <description>1 to 63 cycles</description>
    <value>0x8</value>
  </enumeratedValue>
  <enumeratedValue>
    <name>MOD_1_63</name>
    <description>1 to 63 cycles</description>
    <value>0x9</value>
  </enumeratedValue>
</enumeratedValues>

Leads to code like:

#[doc = "Initialization Delay Modulus\n\nValue on reset: 0"]
#[derive(Clone, Copy, Debug, PartialEq, Eq)]
#[repr(u8)]
pub enum RrInitmod {
    #[doc = "0: 63 cycles (same as 111111b)"]
    Mod63 = 0,
    #[doc = "1: 1 to 63 cycles"]
    Mod1_63 = 1,
    #[doc = "2: 1 to 63 cycles"]
    Mod1_63 = 2,
    #[doc = "3: 1 to 63 cycles"]
    Mod1_63 = 3,
    #[doc = "4: 1 to 63 cycles"]
    Mod1_63 = 4,
    #[doc = "5: 1 to 63 cycles"]
    Mod1_63 = 5,
    #[doc = "6: 1 to 63 cycles"]
    Mod1_63 = 6,
    #[doc = "7: 1 to 63 cycles"]
    Mod1_63 = 7,
    #[doc = "8: 1 to 63 cycles"]
    Mod1_63 = 8,
    #[doc = "9: 1 to 63 cycles"]
    Mod1_63 = 9,
}

#[doc = "Field `RR_INITMOD` writer - Initialization Delay Modulus"]
pub type RrInitmodW<'a, REG> = crate::FieldWriter<'a, REG, 6, RrInitmod>;
impl<'a, REG> RrInitmodW<'a, REG>
where
    REG: crate::Writable + crate::RegisterSpec,
    REG::Ux: From<u8>,
{
    #[doc = "63 cycles (same as 111111b)"]
    #[inline(always)]
    pub fn mod_63(self) -> &'a mut crate::W<REG> {
        self.variant(RrInitmod::Mod63)
    }
    #[doc = "1 to 63 cycles"]
    #[inline(always)]
    pub fn mod_1_63(self) -> &'a mut crate::W<REG> {
        self.variant(RrInitmod::Mod1_63)
    }
    #[doc = "1 to 63 cycles"]
    #[inline(always)]
    pub fn mod_1_63(self) -> &'a mut crate::W<REG> {
        self.variant(RrInitmod::Mod1_63)
    }
    #[doc = "1 to 63 cycles"]
    #[inline(always)]
    pub fn mod_1_63(self) -> &'a mut crate::W<REG> {
        self.variant(RrInitmod::Mod1_63)
    }
    #[doc = "1 to 63 cycles"]
    #[inline(always)]
    pub fn mod_1_63(self) -> &'a mut crate::W<REG> {
        self.variant(RrInitmod::Mod1_63)
    }
    #[doc = "1 to 63 cycles"]
    #[inline(always)]
    pub fn mod_1_63(self) -> &'a mut crate::W<REG> {
        self.variant(RrInitmod::Mod1_63)
    }
    #[doc = "1 to 63 cycles"]
    #[inline(always)]
    pub fn mod_1_63(self) -> &'a mut crate::W<REG> {
        self.variant(RrInitmod::Mod1_63)
    }
    #[doc = "1 to 63 cycles"]
    #[inline(always)]
    pub fn mod_1_63(self) -> &'a mut crate::W<REG> {
        self.variant(RrInitmod::Mod1_63)
    }
    #[doc = "1 to 63 cycles"]
    #[inline(always)]
    pub fn mod_1_63(self) -> &'a mut crate::W<REG> {
        self.variant(RrInitmod::Mod1_63)
    }
    #[doc = "1 to 63 cycles"]
    #[inline(always)]
    pub fn mod_1_63(self) -> &'a mut crate::W<REG> {
        self.variant(RrInitmod::Mod1_63)
    }
}

This is one example of many in the generated output. Am I holding this wrong? There isn't any output from svd2rust to indicate that I might be doing something wrong.

Here is the command I'm running:
svd2rust -i S32K344_M7.svd -o src --target cortex-m -s --atomics --keep-list

Start with the duplicated RR_INITMOD enumeratedValue entries in S32K344_M7.svd and reproduce the output using the reported svd2rust command. Trace how those entries become the RrInitmod enum and writer methods under src; determine and test the expected handling so generation no longer produces uncompilable duplicate definitions.
